Mr. Nesmith

Mr. Nesmith (voiced by Bob Joles) is an intelligent American chimpanzee and Jimmy's Planet Sheen counterpart. Apperently his brain cells have been enhanced after he broke into Zeenu's atmosphere. He seems to be a replacement for Jimmy. There's way more to this chimp than a name tag. He is a master of all things intellectual including math, science and sudoku. He has been camping out on Zeenu since his rocket crashed there back in the '60s. Nesmith always tries to warn Sheen of the consequences of his selfish and dumb choices, but Sheen doesn't listen and does what he wants instead.
