Is Eye of Cthulhu breedable?

Yes. 11 parent pairs produce Eye of Cthulhu.

Where does Eye of Cthulhu sit in the breeding order?

Its CombiRank is 3100, and on a range that runs 20 to 3,100 that places Eye of Cthulhu in the upper third. Ranks are the only thing that decides whether a pair works: the two parents average to floor((rank A + rank B + 1) / 2), and the breedable Pal nearest that average is what hatches.

Is Eye of Cthulhu worth keeping for base work?

Its strongest job is transporting at level 4, and it is a standard Pal at Paldeck #10000.

Does a cake change what Eye of Cthulhu eggs hatch into?

No, not for a normal hatch, and Eye of Cthulhu still arrives in a Large Dark Egg. The species comes from the two parents' ranks, or from the fixed-combination list if the pair is on it, so the Cake you feed them is beside the point for Eye of Cthulhu. Rank 3100 is what decides the child here; the advanced recipes only change what comes with the hatch: egg count, stat growth, passive inheritance, and two of them also improve the mutation roll.

Eye of Cthulhu breeding steps

1. Build a Breeding Farm

A Breeding Farm with Cake in a nearby chest is the whole setup. The 11 parent pairs on this page are the input: check them against your Palbox before you spend Cake on a wild Pal.
2. Assign the two parents

Drop one male and one female into the farm, for example Eye of Cthulhu and Green Slime. Which one goes in which slot makes no difference to Eye of Cthulhu. The one exception in the whole table is a single gendered combination.
3. Collect and incubate the egg

Pick up the egg and put it in an Egg Incubator. Eye of Cthulhu arrives in a Large Dark Egg, and that egg type comes with the species rather than with the pair.
4. Repeat for passives

Keep the pair in the farm and the passives reroll from egg to egg; Eye of Cthulhu keeps hatching, only the passives and the stat growth change.
