Guide

Gooey - Passive Ability
When this Pokémon is hit by an attack, there is a chance it will spread slime around itself. The slime deals damage to Pokémon, Decreases their attack speed by 50% for 2s and applies a Gooey debuff. The Gooey debuff slows Pokémon by 8% for 6s and can stack up to 4 times per Pokémon. Gooey is a debuff that is applicable to Wild Pokémon and enemy players only. When this Pokémon enters tall grass, it continually recovers HP for up to 3s, until it leaves the tall grass, uses a move, or attacks. When this Pokémon recovers HP due to Gooey, its attack gauge is progressed towards a boosted attack. This HP recovery goes on a 12s cooldown after being triggered.

Attack - Auto Attack
Becomes a boosted attack with every third attack, dealing increased damage. Hitting a Pokémon afflicted with a Gooey effect with a basic attack reduces all of this Pokémon's move cooldowns by 1.5s.
