Bathtub

The Bathtub is a walking bathtub that Lock, Shock, and Barrel of Halloween Town use to get around in.

Kingdom Hearts II
The Nightmare Before Christmas (1993)

''The walking bathtub Lock, Shock, and Barrel use to get around. It's also big enough to carry any mischief-making tools they need to bring along.''

Kingdom Hearts
It serves as Lock, Shock, and Barrel's transporting item. When Sora, Donald, Goofy and Jack go to Oogie's House, they can use Bathtub as transport when they fall off the house.

Kingdom Hearts II
Lock, Shock, and Barrel's Bathtub only shows up once in this game, where it takes the trio around Halloween Town until they encounter Maleficent.
