A mentally unstable green monkey that is also the generation 8 grass-type starter Pokémon. For some unknown reason people who likes to draw fanart, often draw Grookey with a gun. People who pick Grookey as their starter are known as part of the Grookey Gang.

Grookey will have two other evolved forms, but those are not revealed, as of March 2019.
Person 1 "I'm going to pick Sobble for my gen 8 starter."
Person 2 "Hell no, Grookey Gang for life, baby!"

A thing people convince themselves it's real when it doesn't exist.
"Yo I can't wait until Grookeys finally in the Anime"

"It doesn't exist stop living in a fantasy world"
