Pumpkaboo

Pumpkaboo (Japanese: バケッチャ Bakeccha) is a dual-type Ghost/Grass Pokémon introduced in Generation VI. It resembles a jack-o'-lantern pumpkin with a thick shag of dark brown hair, a curled stem, and horn-like tufts of hair. A mysterious orange light glows within its body. Pumpkaboo comes in various sizes, from small to super-size, which affect its stats, with larger Pumpkaboo having higher HP but lower speed. It is said to carry wandering spirits to where they belong so they can move on, with smaller ones preferring children's souls and larger ones adults'. Pumpkaboo can hypnotize and control other Pokémon or humans by releasing light from the holes carved into its body. It evolves into Gourgeist when traded. It's also the only known Pokémon that can learn the move Trick-or-Treat. In Pokémon GO, Pumpkaboo also appears in four sizes, and each can have a decorated version.
