Contact with the Pokémon lowers the attacker's Speed stat.
Gooey is an ability introduced in Generation VI. So far, 2 Pokémon have this ability.
When a Pokémon with this Ability is hit by a move that makes contact, the Speed of the attacking Pokémon is decreased by one stage.
If a Pokémon with this Ability is hit by a multi-strike move that makes contact (such as Fury Swipes), each hit activates this Ability.
It can be seen as a more focused version of the new generation 8 ability, Cotton Down, since unlike Cotton Down, Gooey only lowers the speed of the attacking Pokémon rather than all Pokémon around it.
Outside of battle
Gooey has no effect outside of battle.
