★ special combo — a fixed pair that overrides the usual rule. Lv = lowest level the Pal spawns at in the wild on Palpagos; “bred” = it does not spawn there.
Or hatch it

Jellroy hatches from a Damp Egg. Wild nests draw their egg from a weighted table, so any of the 1,786 nests on the map can hold one and none promises it. Incubate it cold: Place a Cooler (any tier) next to the incubator, or build in a snowy/desert-cold biome. All 1,786 nests on the map →
How breeding works
- 1Reach Tech Level 19 to unlock the Breeding Farm; place it on your base.
- 2Build 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.
- 3Catch the parent pair you picked above — one male and one female.
- 4Pick up each parent and drop them into the Breeding Farm fence. Place the Cake in the feed box just outside.
- 5Wait about five minutes of real time for the yellow breeding circle to complete; an egg will appear in the farm.
- 6Place the egg into an Egg Incubator. After it hatches you have your Jellroy.
