Shrinkbarrel

The Mini Barrel is an object in the game Wario Land: Shake It It can only be found in two levels: Bad Manor and Boogie Mansion. It resembles a brown barrel with two yellow arrows and two openings, one big and the other small. When Wario enters the large opening, he turns into Mini Wario. Mini Wario can fit through small openings and find hidden treasure. When Mini Wario enters the smaller opening of the barrel, he turns back to normal. These arrels are somewhat rare.
