Mr. Nesmith

Mr. Nesmith is a brilliant American chimp who happens to share a last name with the bassist from '60s TV band, The Monkees. Coincidence? Who cares! There's way more to this Chimp than a name tag. Heis a master of all things intellectual -- math, science, sudoku, you name it -- who has been camped out on Planet Zeenu since his rocket crashed there back in the '60s (hey!). Though he may not be the world's most tolerant monkey when it comes to Sheen's antics, Nesmith's rocket fixing skills make him our hero's best shot at getting home.
