That's what others have said, since the company that makes Pokemon Kids also makes statutes the same size for other animes/games. So it could have been included because someone thought it was a Pokemon, or because it is a Pokemon. I'm hoping that it is a Pokemon. Even if it wasn't, it's still pretty epic for being a broccoli-monkey saying things are "this big!"Their is a chance I read in Pokebeach that the green one might not even be a pokemon at all...
Maybe this is how the baby looks after it leaves it's moms pouch :)?!
