One Piece Chapter 22, page 11: YOU ARE A RARE AND PRECIOUS ANIMAL TOO

Luffy bluntly calls Gaimon's situation stupid, infuriating the chest-man. Gaimon laments that his hair, mustache, and eyebrows have grown wild over the last twenty years. Luffy tries to pull Gaimon out of the chest by his head, but Gaimon screams in pain, warning that his body and the chest have fused together over the years and pulling him out will kill him. Nami asks how he ended up on the island in the first place.
