How to breed Rainbow Slime, step by step
- Get the parents. The cheapest route is Green Slime + Cave Bat; any other pair from the table below works too. You need one male and one female — genders of the two species are interchangeable.
- Set up the Breeding Farm. Assign both parents to the farm and stock the chest with cake — breeding does not start without it. Keep a steady cake supply going if you plan to hatch multiple eggs.
- Collect and incubate the egg. The pair produces an egg that hatches into Rainbow Slime. Pop it in an incubator; Dynamoff at your base and the Babysitter passive both cut the waiting time.
- Breed for passives. The baby can inherit up to four passive skills from its parents, and every egg has a small chance to mutate with boosted stats. Hatch in bulk until you get the Rainbow Slime you want.
