Rillaboom (Japanese: ゴリランダー Gorirandā) is a Grass-type Pokémon introduced in Generation VIII.
It evolves from Thwackey starting at level 35. It is the final form of Grookey.
By drumming, Rillaboom taps into the power of its special tree stump. The roots of the stump follow its direction in battle.
The Rillaboom with the best drumming techniques becomes the boss of the troop. It has a gentle disposition and values harmony among its group.
