First time breeding? Read the universal walkthrough
The Breeding Farm process is the same for every Pal — pick one of the 8 pairs above, drop both parents in, and feed them a Cake. The Pindrop calculator handles the parent-pair maths; the workflow is universal.
- Reach Tech Level 19 to unlock the Breeding Farm; place it on your base.
- Build a Cooking Pot (Tech Level 17) and bake a Cake from 5 Flour, 8 Red Berries, 7 Milk, 8 Eggs, and 2 Honey. Without the Cake the parents will not produce an egg.
- Catch the parent pair you picked above — one male and one female.
- Pick up each parent and drop them into the Breeding Farm fence. Place the Cake in the feed box just outside.
- Wait roughly four minutes (in-game time) for the yellow breeding circle to complete; an egg will appear in the farm.
- Place the egg into an Egg Incubator. After it hatches you have your Rainbow Slime.
Frequently asked
Can you breed Rainbow Slime in Palworld?
Yes — there are 17 viable parent combinations (including 16 unique combos that always produces Rainbow Slime regardless of breeding-power averaging). Pair any of them in a Breeding Farm (Tech Level 19) with a Cake to start hatching Rainbow Slime.
What two Pals make Rainbow Slime in Palworld?
The unique pair Cave Bat + Green Slime always produces Rainbow Slime, regardless of breeding-power averaging. 7 additional unique combos also work.
What level do I need to breed Rainbow Slime in Palworld?
The Breeding Farm itself unlocks at Tech Level 19 — that's the gating requirement, not the parents' combat level. Both parents need only be captured (any level), opposite gender, and fed Cake in the farm's feed box. Cake is baked at a Cooking Pot (Tech Level 17) from 5 Flour, 8 Red Berries, 7 Milk, 8 Eggs, and 2 Honey.
Can Rainbow Slime be bred in the early game?
Yes — the easiest pair uses Pals with rarity ≤ 3, which are catchable in the early-to-mid game. Once the Breeding Farm is built (Tech Level 19), you can hatch Rainbow Slime well before reaching the late-game encounters.
