Pals born with Hydromaniac (0)
No Pal is guaranteed to spawn with Hydromaniac. To get it, breed from a parent that already has it — the passive can then be inherited by the child.
How to pass Hydromaniac down
In Palworld, a child can inherit passive skills from either parent. To put Hydromaniac on a target Pal, breed it from a parent that carries Hydromaniac, then keep breeding the offspring toward your target species while retaining the passive. Use the breeding calculator to find the parent combos.
Passive-inheritance probabilities are community estimates, not official Pocketpair figures.
