Chopper's breather concludes as Kumadori frees himself from the fridge, apparently after he finished eating its contents. At first, he is fat, but he digests all the food immediately and is slim again. Fascinated, Chopper asks how he did it. Kumadori willingly explains. Afterwards, the two resume their fight where it had stopped. Chopper quickly realizes that he cannot break through Kumadori's body-hardening technique without the effect of his Rumble Ball drug. Having used a first while rescuing Nami, he dares not use a second out of fear of its side effects. Nevertheless, he takes it. Chopper charges repeatedly, but his transformations are erratic and difficult to control. By the time he assumes the correct form, he is too weak and is struck down. Left with one choice, he steps into the forbidden realm of taking a third Rumble Ball.
