Which breeding power does Blue Slime use?

Blue Slime sits at breeding rank 3100, in the upper third of the 20–3,100 range. The game averages the two parents' hidden ranks as floor((rank A + rank B + 1) / 2) and hatches the breedable Pal nearest that number, which is how the pairs listed below reach Blue Slime.

What is Blue Slime good at around the base?

Its strongest job is transporting at level 1, and it is a standard Pal at Paldeck #10003.

Can cakes improve Blue Slime eggs?

A Cake will not change what Blue Slime hatches into. The pair decides the species before the egg exists, the egg is a Damp Egg, because of the two ranks rather than the recipe. The advanced cakes move what comes with the hatch instead: how many eggs a run produces, how fast Blue Slime grows, how likely a passive is to carry over, and how likely a mutation is.

Blue Slime breeding steps

1. Build a Breeding Farm

Place a Breeding Farm at your base and keep Cake in a nearby chest. Cake is the one thing breeding will not start without, and this page already lists 2 parent pairs, so pick the pair you can make today.
2. Assign the two parents

Assign Green Slime and Blue Slime, one of each gender. The pairing is what matters rather than which side each of them sits on: swap them and Blue Slime still hatches, unless the pair happens to be the one gendered special combination.
3. Collect and incubate the egg

Pick up the egg and put it in an Egg Incubator. Blue Slime arrives in a Damp Egg, and that egg type comes with the species rather than with the pair.
4. Repeat for passives

For Blue Slime the species is settled by the first egg and never moves again. What you reroll by breeding the pair a second time is the passives and the stat growth.
