Ability & mechanics
Its fruit-eating chance stacks the Big (x1.25) and Rainbow (x1.15) multipliers on the base 3.5% per-second eat chance, for a combined multiplier of roughly x1.44, still on an 8-second cooldown between bites. After 8 fruit, it lays an egg within 10 to 30 seconds that hatches a pet matching the fruit consumed.
