Slime Rancher 2 has over 20 distinct slime types spread across three biomes, and knowing every one of them — where to find them, what to feed them, and how to manage them in a corral — is the foundation of an efficient ranch. This Slime Rancher 2 all slimes guide covers every slime using a consistent six-field overview system: location, favourite food, plort produced, largo risk level, special behaviour, and a practical ranch management tip.
Some slimes are easy neighbours. Others blow up, steal food, or require entirely different infrastructure. This guide separates them clearly so you can build a ranch that runs smoothly rather than one that constantly fights against itself. If you are brand new to the game, start with our Slime Rancher 2 beginner’s guide for the core mechanics before focusing on individual slime management.

Rainbow Fields Slimes
Rainbow Fields is the starting biome and home to the most accessible slimes in the game. These are the slimes you encounter first, and several of them form the backbone of most early- and mid-game ranching operations. Understanding their individual behaviours prevents the most common new rancher mistakes — particularly the food theft and escape problems that catch players off guard before they understand the mechanics.
Pink Slime
| Field | Detail |
|---|---|
| Location | Rainbow Fields — the most abundant slime in the game |
| Favourite Food | None — eats any food type (true omnivore) |
| Plort Produced | Pink Plort — lowest market value in the game |
| Largo Risk | Low — creates the safest and cheapest largo combinations |
| Special Behaviour | No special mechanics; entirely passive |
| Ranch Tip | Use pink largos to test new food setups without requiring a second food type; omnivore trait means one food source handles any pink largo combination |
Pink slimes are the game’s starter slime for a reason. They ask nothing unusual of you — any food works, no special corral upgrades required, and their passive behaviour means they will not interfere with adjacent corrals. Pink plorts have low individual value, but that is offset entirely by how frictionless they are to produce. Their real value is in largo combinations: a pink largo inherits the other slime’s favourite food and dietary preferences, but since pink slimes eat anything, you only need to stock the non-pink half’s preferred food. This makes pink largos the most food-efficient largo type in the game, especially early when food variety is limited and supply chains are still being built.
Cotton Slime
| Field | Detail |
|---|---|
| Location | Rainbow Fields |
| Favourite Food | Water Lettuce (veggie) |
| Plort Produced | Cotton Plort — solid early-game value |
| Largo Risk | Low — fully manageable once Air Net corral upgrade is installed |
| Special Behaviour | Jumps extremely high — will clear standard unupgraded corral walls consistently |
| Ranch Tip | Air Net upgrade is mandatory before housing cotton slimes; without it, escape events will happen constantly |
Cotton slimes look harmless but their jump height is the biggest surprise for new ranchers. A corral without an Air Net is not a functional cotton corral — they clear the walls reliably and scatter across your ranch. Once the Air Net is installed, they settle into an efficient and low-maintenance slime. Water Lettuce grows steadily in garden plots and is not in high demand from other slime types at this stage, which means cotton plort income is easy to sustain without complex food logistics. Cotton slimes are one of the best second or third corral investments after pink slimes are established.
Tabby Slime
| Field | Detail |
|---|---|
| Location | Rainbow Fields |
| Favourite Food | Hen Hen (meat) |
| Plort Produced | Tabby Plort — above-average early value |
| Largo Risk | Medium — food theft mechanic causes problems in dense ranch setups |
| Special Behaviour | Actively steals food and plorts from adjacent corrals if not isolated by placement |
| Ranch Tip | Place tabby corrals at the edge of your ranch, away from all other slime types; food theft creates a hidden efficiency drain in neighbouring corrals |
Tabby slimes are playful but problematic neighbours. They actively hunt for food and plorts near their corral, depleting neighbouring food supplies and creating a management problem that is not immediately obvious. Your other slimes appear underfed for no clear reason — the actual cause is the tabby corral nearby silently claiming their food. The fix is pure placement: put tabby corrals at the far end of your ranch or separate them with a buffer zone. Once isolated, they are a reliable income source. Hen Hen is easy to maintain and tabby plorts have solid market value for the early game.
Boom Slime
| Field | Detail |
|---|---|
| Location | Rainbow Fields (edge zones) and Ember Valley |
| Favourite Food | Briar Hen (meat) |
| Plort Produced | Boom Plort — mid to high value |
| Largo Risk | High — explosions affect adjacent corrals and distress neighbouring slimes |
| Special Behaviour | Detonates on proximity contact; group explosions chain-react and amplify damage |
| Ranch Tip | Corral Bumpers upgrade is essential; isolate boom corrals completely from all other slime types without exception |
Boom slimes are the first genuinely hazardous slime most ranchers encounter. They detonate on proximity — not just toward the player, but toward adjacent slimes and corral walls too. A boom corral placed next to another corral triggers chain-reaction events that launch plorts, damage upgrade infrastructure, and continuously distress the slimes inside neighbouring enclosures. Briar Hen is only found in Ember Valley, which naturally prevents early boom ranching until the second biome is accessible. Once you have the area unlocked, Corral Bumpers installed, and the boom corral positioned in strict isolation, boom plorts are worth the infrastructure cost. The key word is isolation — no exceptions.
Ember Valley Slimes
Ember Valley is the volcanic second biome, home to the game’s most management-demanding slimes. Each one requires either specific food types only available in this biome, special corral upgrades to contain them safely, or unique infrastructure that has no equivalent elsewhere on the ranch. The investment is worth making: Ember Valley slimes produce higher-value plorts than most Rainbow Fields residents, and unlocking the full Ember Valley operation is a significant mid-game income step.
Rock Slime
| Field | Detail |
|---|---|
| Location | Ember Valley |
| Favourite Food | Heart Beet (veggie) |
| Plort Produced | Rock Plort — reliable mid-game value |
| Largo Risk | Low — passive, slow-moving, no disruptive mechanics |
| Special Behaviour | Rolls slowly around the corral, bouncing off walls harmlessly |
| Ranch Tip | The easiest Ember Valley introduction; pair with a Heart Beet garden plot for low-effort passive income with no upgrade requirements beyond a standard corral |
Rock slimes are Ember Valley’s most accessible residents. Their rolling behaviour is cosmetic — it causes no damage, no food theft, no infrastructure stress, and no special upgrade requirements. Heart Beet is a reliable veggie crop that grows well in garden plots. If you want a low-friction Ember Valley income stream while you build the more demanding infrastructure for crystal and boom slimes, rock slimes are the correct first step. They deliver consistent returns from a standard corral and a basic vegetable garden, with nothing unusual required.
Crystal Slime
| Field | Detail |
|---|---|
| Location | Ember Valley |
| Favourite Food | Odd Onion (veggie) |
| Plort Produced | Crystal Plort — mid-high value |
| Largo Risk | High — launches crystal spike projectiles when agitated, damaging adjacent corrals |
| Special Behaviour | Shoots crystal shards outward when disturbed, crowded, or underfed |
| Ranch Tip | Keep crystal corrals isolated and feed on a consistent schedule — agitation events trigger spike projectiles that damage and distress neighbouring slimes |
Crystal slimes are profitable but demanding neighbours. When agitated — triggered by crowding, infrequent feeding, or general stress — they launch crystal spikes outward that damage adjacent corral structures and distress the slimes inside them. The management strategy mirrors boom slimes: strict isolation and regular feeding to prevent agitation from building. Odd Onion is available in Ember Valley and grows in garden plots once the biome is unlocked. With proper placement and a reliable food supply, crystal plorts deliver strong returns for the effort level required.
Fire Slimes — Special Ranch Infrastructure Required
Fire slimes are the most unique ranch management case in the game. They operate under completely different rules from every other slime type. A standard corral cannot house fire slimes — placing fire slimes in a standard corral will kill them. They require an Ash Trough, a dedicated piece of infrastructure available from the Builder’s Shop after unlocking Ember Valley. The Ash Trough is not an upgrade to a standard corral; it is a separate, purpose-built enclosure that functions on entirely different principles.
| Field | Detail |
|---|---|
| Location | Ember Valley — near volcanic and lava flow areas |
| Favourite Food | Ash — produced by incinerating food items in the Ash Trough |
| Plort Produced | Fire Plort — mid-value with specific crafting applications |
| Largo Risk | N/A — cannot form largos due to non-standard housing requirement |
| Special Behaviour | Burns on contact with water; requires Ash Trough to survive on the ranch |
| Ranch Tip | Establish a reliable ash supply chain before collecting fire slimes — the Ash Trough requires regular replenishment from incinerated surplus food items |
Fire plorts are worth adding to your ranch for their crafting utility — they unlock several gadgets and upgrades that improve ranch-wide efficiency. The infrastructure cost is real: the Ash Trough occupies a builder slot, requires an ash production step separate from your main food operations, and produces no plorts from standard feeding since fire slimes eat ash rather than food. Your garden plots and hen houses are entirely irrelevant to fire slime maintenance. Build the ash production loop first — incinerate surplus food items to keep the trough consistently stocked — before committing the builder slot. The plort income does not justify the setup cost without an established ash supply already running reliably.
Phosphor Slimes — Night Corral Management
| Field | Detail |
|---|---|
| Location | Rainbow Fields at night; sheltered and shaded areas during daytime |
| Favourite Food | Cuberry (fruit) |
| Plort Produced | Phosphor Plort — good value with minimal food competition from other slimes |
| Largo Risk | Medium — fully manageable once Solar Shield upgrade is installed |
| Special Behaviour | Takes continuous damage from direct sunlight during daytime hours; glows at night |
| Ranch Tip | Solar Shield corral upgrade is non-negotiable — unshielded phosphor slimes take persistent sun damage all day and will eventually die from it |
Phosphor slimes are the most important early investment in specialised corral infrastructure. The Solar Shield upgrade is not optional — without it, your phosphor slimes receive continuous sun damage during daylight hours and will eventually die. The upgrade resolves the problem completely, after which phosphor slimes become a reliable and low-friction income stream. Cuberry is a fruit type that is not heavily contested by other slime types early in the game, so maintaining a dedicated Cuberry garden plot supports phosphor plort output without disrupting other food chains. One upgrade investment, then consistent passive returns.
Starlight Strand Slimes
Starlight Strand is the third biome and home to the game’s most valuable slimes alongside its most demanding food supply requirements. The food types here — Mint Mango, Moondew Nectar, Sea Hen — are harder to produce in quantity than anything available in the earlier biomes. The reward for investing in those supply chains is access to some of the highest plort income in the game, and slimes whose behaviour, once the food logistics are solved, is either passive or manageable.
Honey Slime
| Field | Detail |
|---|---|
| Location | Starlight Strand |
| Favourite Food | Mint Mango (fruit) |
| Plort Produced | Honey Plort — high value |
| Largo Risk | High — actively pulls food from adjacent corrals, starving nearby slimes |
| Special Behaviour | Extremely sticky; draws food items from neighbouring corrals into their own feeding area |
| Ranch Tip | Honey corrals must be fully isolated from all other food-eating slimes — nearby placement causes constant food shortages across your entire ranch |
Honey slimes produce some of the highest-value plorts available in the mid-to-late game, but their food-pulling mechanic is one of the most disruptive in the entire system. A honey corral placed near any other corral will continuously drain that corral’s food supply. Your other slimes appear underfed without any obvious reason — the actual cause is the honey corral nearby silently drawing food away. The solution is complete spatial isolation: build honey corrals at the far end of your ranch, well separated from every other food-eating slime. Once the isolation is in place and a dedicated Mint Mango garden is running, the income-to-effort ratio on a properly positioned honey corral is among the best available.
Flutter Slime
| Field | Detail |
|---|---|
| Location | Starlight Strand — rare spawn, harder to locate than most other slime types |
| Favourite Food | Moondew Nectar — only harvestable from nectar plants during night hours |
| Plort Produced | Flutter Plort — among the highest value in the game |
| Largo Risk | Low — completely passive; no disruptive mechanics of any kind |
| Special Behaviour | Floats gently; very rare in the wild; entirely non-aggressive and non-disruptive |
| Ranch Tip | Build your Moondew Nectar supply infrastructure before catching flutter slimes — the night-only harvest window must be addressed before committing corral space |
Flutter slimes are the most valuable ranchable slime type in the game. Their plort value sits at the top of the income hierarchy, their behaviour is completely passive — no explosions, no theft, no special corral requirements beyond a standard setup — and the only real challenge is the food supply. Moondew Nectar only comes from specific nectar plants that can be harvested at night, creating a time-constrained collection window that requires active management or a dedicated cultivation system. Establish the nectar supply chain before committing corral space, and flutter slimes become one of the cleanest high-value operations on a mature ranch. For optimised largo pairings using flutter plorts, see our Slime Rancher 2 largo guide.
Angler Slime
| Field | Detail |
|---|---|
| Location | Starlight Strand — water zones and coastal areas |
| Favourite Food | Sea Hen (meat) |
| Plort Produced | Angler Plort — mid-high value |
| Largo Risk | Medium — passive behaviour, but lure appendage has minor effects on nearby items |
| Special Behaviour | Uses bioluminescent lure appendage to attract nearby objects; found in and near water environments |
| Ranch Tip | Sea Hen must be sourced from Starlight Strand hen houses — plan food infrastructure placement around this biome constraint before setting up the corral |
Other Notable Slimes
Ringtail Slime
| Field | Detail |
|---|---|
| Location | Ember Valley and Starlight Strand |
| Favourite Food | Any food (omnivore, like pink slime) |
| Plort Produced | Ringtail Plort — mid-range value |
| Largo Risk | Low — daytime petrification eliminates overnight ranch management complexity |
| Special Behaviour | Fully petrifies during daylight hours — completely immobile, produces no plorts, requires no feeding while in stone form |
| Ranch Tip | All plort production is compressed into evening and night hours — active management during those windows is required to capture the full output |
Ringtail slimes were added in version 1.0 and bring a genuinely novel mechanic to the game. During daylight hours they turn completely to stone — immobile, unable to eat, unable to produce plorts, and unable to escape. This makes them unusually low-pressure slimes: no daytime feeding requirement, no escape risk, no management complexity while most players are active on their ranch. The trade-off is that all plort production concentrates into the evening and night windows, so players who are most active during those hours get the most from a ringtail corral. Their omnivore food preference means any food type works, which keeps logistics simple and removes any food competition concerns.
Batty Slime
Batty slimes inhabit the cave sections of Starlight Strand and prefer Pomegranite, producing batty plorts with above-average value. They are more active during night hours but, unlike phosphor slimes, they do not take sunlight damage during the day and require no special corral upgrades beyond a standard setup. Their behaviour is entirely passive and non-disruptive toward neighbouring corrals, making them a straightforward late-game addition once Starlight Strand is accessible. Pomegranite can be grown in garden plots within the biome, giving batty corrals a dedicated food supply without cross-biome logistics.
Puddle Slime
Puddle slimes inhabit water areas across all three biomes and sustain themselves on water rather than standard food — garden plots and hen houses are entirely irrelevant to maintaining them. Puddle plorts have relatively low market value but serve a specific role as largo combination ingredients in certain setups. Their largo potential is limited by the water environment requirement, which constrains the practical combinations available. Puddle slimes are a targeted addition for ranchers building specific plort portfolios rather than a general income recommendation for new ranchers still establishing core operations.
Gold Slime
Gold slimes are unique: they cannot be caught or ranched under any circumstances. They spawn randomly in all three biomes and flee immediately when they detect a nearby rancher. The only way to profit from a gold slime encounter is to quickly throw their specific favourite food at them — Gilded Ginger, Kookadoba, or Strange Diamond — which causes them to scatter gold plorts on the ground before running. Gold plorts have very high value but disappear quickly if not collected immediately. Keep at least one gold-slime food type in your inventory at all times specifically for these encounters. Speed is critical — hesitation means missed plorts.
Lucky Slime
Lucky slimes are rare random spawns that appear in all biomes. They prefer meat and drop Newbucks coins rather than plorts when fed — the payout per interaction is above average for a single encounter. Like gold slimes, they are an opportunistic income source rather than a ranchable resource. Carry their preferred food type, engage when they appear, collect the coins. Lucky slimes are not part of any ranch planning calculation but provide a meaningful windfall when the encounter happens at the right moment during an active session.
Slime Temperament Guide: Safe Neighbours and Isolation Rules
Corral placement is one of the most consequential decisions in ranch design. Slimes with disruptive mechanics will silently undermine nearby corrals without obvious warning signs, and the efficiency loss compounds over time. Use this reference table when planning your corral layout. For full ranch design strategy and corral arrangement principles, see our Slime Rancher 2 ranch layout guide.
| Slime | Safe to Neighbour? | Reason |
|---|---|---|
| Pink Slime | Yes | Fully passive; no disruptive mechanics |
| Rock Slime | Yes | Slow rolling only; no food theft or projectiles |
| Cotton Slime | Yes (with Air Net) | Jump mechanic only affects their own corral once Air Net is installed |
| Ringtail Slime | Yes | Petrified during the day; no interaction with neighbours while in stone form |
| Flutter Slime | Yes | Completely passive; no disruptive tendencies of any kind |
| Phosphor Slime | Yes (with Solar Shield) | Sunlight damage is internal; does not affect adjacent corrals |
| Angler Slime | Yes | Lure mechanic has minimal practical impact on neighbouring corrals |
| Batty Slime | Yes | Passive behaviour; nocturnal but no disruptive mechanics |
| Tabby Slime | No | Steals food and plorts from adjacent corrals continuously |
| Honey Slime | No | Pulls food from nearby corrals, causing starvation in neighbouring slime populations |
| Boom Slime | No | Explosions damage adjacent corral structures and distress all nearby slimes |
| Crystal Slime | No | Crystal spike projectiles damage adjacent corrals when agitated |
| Fire Slime | No (Ash Trough only) | Cannot be housed in standard corrals at all — requires dedicated infrastructure |
| Puddle Slime | Situational | Water environment requirement determines placement; assess based on available water access |
Best Slimes to Ranch First
Not every slime is worth pursuing early. These five deliver the best return relative to setup complexity during your first hours of ranching on Rainbow Island:
- Pink Slime — The correct starting point. No food preference, no upgrade requirements, no disruptive behaviour. Pink largos let you test new food types without stocking a second food source. Use them to build the initial income base while gathering resources for more specialised corrals.
- Cotton Slime — After the Air Net upgrade, cotton slimes offer strong early plort value with simple and predictable food costs. Water Lettuce grows efficiently and competes with nothing else in your early food chain, making cotton income a clean dedicated revenue stream from the moment the corral is upgraded.
- Phosphor Slime — The Solar Shield is a one-time investment that unlocks reliable ongoing returns. Cuberry faces minimal competition from other slimes in the early game, so a Phosphor corral has a clean dedicated food supply and consistent output after a single upgrade purchase. One upgrade cost, then low-friction passive production.
- Rock Slime — The safest Ember Valley starting point. Heart Beet is a straightforward veggie to grow, and rock slimes need nothing beyond a standard corral. Add them as your first Ember Valley income operation while building toward the more demanding boom and crystal setups.
- Honey Slime — High plort value justifies the placement discipline required. Once a dedicated Mint Mango garden is running and honey corrals are isolated at the ranch perimeter, the income-per-corral ratio is among the best available in the mid-to-late game and the ongoing management is straightforward.
Avoid starting with boom slimes, crystal slimes, or fire slimes until you have the specific upgrades and infrastructure they require. Attempting those setups without proper preparation wastes early-game resources and teaches the mechanics in the most painful way possible. Pink, cotton, and phosphor corrals deliver reliable income immediately and build the resource base needed to set up more demanding operations correctly when the time comes.
Frequently Asked Questions
Can every slime type be ranched on the farm?
Almost every slime type can be maintained on your ranch, but gold slimes and lucky slimes are permanent exceptions. Gold slimes flee on sight and can only generate income through timed feeding encounters that cause dropped gold plorts. Lucky slimes drop coins when fed but also cannot be captured or kept. Every other slime type — including fire slimes in their Ash Trough — can be housed on the ranch with the correct infrastructure in place.
Which slimes are the most difficult to manage?
Fire slimes require the most unique infrastructure — the Ash Trough has no equivalent anywhere else in the game and operates on completely different principles from a standard corral. Crystal and boom slimes require the strictest spatial planning due to their projectile and explosion mechanics damaging neighbouring corrals. Flutter slimes are the most difficult from a food supply perspective: Moondew Nectar has the most constrained harvest window in the game and the supply chain must be established and reliably running before committing corral space to flutter slimes.
What is a largo and why does slime knowledge matter for creating one?
A largo forms when a slime eats the plort of a different slime type, merging the two into a hybrid that produces both plort types simultaneously from a single food feeding. Largos are the primary income multiplier mechanism in Slime Rancher 2, and understanding each slime’s individual behaviours before choosing combinations is essential. Some pairings stack disruptive mechanics — combining two food-stealing slimes, for example, creates an extremely problematic largo — while others pair passive behaviours with high plort values for efficient low-maintenance operations. See our complete Slime Rancher 2 largo guide for the most effective combinations.
Do slimes escape from corrals?
Several slime types will escape specific corral configurations. Cotton slimes jump out of any corral without an Air Net upgrade. Boom slimes can damage corral walls through explosion events if Corral Bumpers are not installed, creating gaps in containment. Tabby slimes are unusually active and can escape in poorly maintained or understaffed corrals. The consistent rule across all these cases: always install the required upgrade before placing a slime type with known escape mechanics. The upgrade cost is negligible compared to losing a full corral of slimes and spending time recapturing them.
