Pumpkaboo

Pumpkaboo is a bipedal Pokémon that resembles a pinkish pumpkin. It comes in four different sizes: small, average, large, and super sized. The pumpkin body has a pair of circular holes carved out of its rind that resemble eyes. The ghostly body that lives in the pumpkin is black with a pointy collar, yellowish eyes with no visible pupils, a pair of fangs, curved ears and a curled stem. Pumpkaboo can release light from the holes on its body, making it similar to a flashlight.

The spirit residing in the pumpkin is trapped in this world. Pumpkaboo can carry wandering spirits to where they belong, so they can move on. It and its evolution Gourgeist are the only known Pokémon that can learn Trick-or-Treat.
