Fat Wario is one of Wario's many transformations from the Wario Land series of games. To achieve this state, Wario must eat a cake thrown by a Cook, a donut or an apple thrown by an Apple Monkey. This will cause him to swell to immense portions of obesity, allowing him to destroy enemies and certain blocks by simply bouncing them off his stomach, but his Jumping abilities will greatly diminish and he will walk at a snail's pace, although if he jumps, he will automatically Ground Pound when he falls. It can be remedied by walking for awhile or falling into water.
