Pumpkin Banjo

Pumpkin Banjo is the native transformation of Mad Monster Mansion. It has no attacks or remarkable abilities, but its small size allows it to fit into small openings which Banjo and Kazooie would not normally be able to enter. In addition to being used in several puzzles within the world itself, the Pumpkin transformation is needed to access the shack just outside the world entrance (which, in turn, is required to enter to progress in the game), and it also required to squeeze through the hole in the wall just behind Brentilda in the room filled with lava inside the lair immediately before the Mad Monster Mansion room.
