    The only human who was kind to him was Doctor Hiruluk, a crazy doctor who tried to help the sick ad usually made things worse. It was Hiriluk that gave him the name Tony Tony Chopper. Hiriluk fell seriously ill, and Chopper wanted to help him by finding a rare mushroom on the island. He was attacked by his former heard while in the search and seriously injured.
