Munchlax (ゴンベ, Gonbe) is a fictional creature in the Pokémon franchise.
Munchlax is the baby form of Snorlax, and was the very first Generation IV Pokémon ever publicly revealed, making several appearances in Pokémon games even before its playable debut in the main-series games Pokémon Diamond and Pearl. Munchlax is categorized within the Pokédex at #446 as the "Big Eater Pokémon". It evolves into Snorlax when leveled up with high friendship. Munchlax is described as the "Big Eater" Pokémon, and all of its Pokédex entries deal with its eating habits.
Its "move" in Brawl, Pickup, is one of its possible abilities in the Pokémon games: a Pokémon with it might find an item after a battle, and, since Generation V, can pick up items discarded by other Pokémon during a battle.
As a Poké Ball Pokémon
Munchlax is one of the Pokémon that appears out of a Poké Ball. When summoned it wanders aimlessly around the stage, eating any items it finds excluding Poké Balls, Smash Balls, and collectibles (Trophies, CDs, and Stickers). If there aren't any items around for it to gobble up, Munchlax is effectively useless, much like Goldeen.
