Bob-omb

The Bob-omb is a walking mechanical explosive device from Mario's dimension, operated by a wind-up key and timed via fuse, seeing as it resembles an actual bomb. They are typically used in attack and battle situations, often by the Koopa Clan, who are eager to take advantage of the quick access, easy operation, and destructive nature of the Bob-omb. During the Battle on Blorch, Waluigi uses two of these as weaponry to combat and destroy the attacking Shadow Androids.
