Pet Mutations — May 2026

Pet mutations are rarer than crop mutations but they apply permanently to your pet roster. A mutated pet keeps its modifier across hatches and unlocks unique boost tiers — Shiny, Mega, Frozen and so on — that scale that pet's passive ability.

Pet mutations roll inside specific event eggs or during certain weather events. The list below covers every confirmed pet mutation in the game with its multiplier label. Use it to decide which events are worth grinding for ability buffs.
