Ah, I've only heard about that Jinpei thing. It sounds SO. FUNNY! Woops, kinda "Gatcha" off topic. But it'd be the living end if that happened to Chopper, instead of trying a cutesy voice.
Gatcha! Hahahaha ahem Yeah, I guess they had to think of a way of explaining how a little kid could be fighthing in dangerous battles, plus, most of his original dialogue, well, I don't think parents, especially in the 70's would approve of it. ;) And it was actually a child actor who did his voice. So in BotP they turn him into Keyop, the test-tube clone thing that talked like "ffopjofjofijofjsp booopboopp Hi there!". Poor kid was renamed "Peewee" in G-force or something retarded like that, and was voiced by Barbara Goodson.
I don't think they would do something like that to Chopper. He'll probably still have a kid voice. He's a reindeer, he'll probably get away with a lot. :D If they get that far…
…....I'm so sorry. I haven't slept or eaten in 28 hours.
Dang…still waiting for chapter 359?
