Chuckolator

Chuckolator is a fictional monster and a minor villain in Mario & Luigi: All-Star Saga, like many Mario villains it is a parody - in this case of soda mascots such as the (in)famous Kool Aid Man.

Chuckolator takes the form of a giant vaguely anthropomorphic can of soda with arms which attacks Mario and Luigi - at first it is shielded with a sword but once its shield is destroyed it resorts to transforming one of its arms into a sword while also attacking with its other arm, which resembles a gun: both attacks tend to spawn slime that does damage unless Mario and Luigi jump over them.
