Well, it's been stated, IIRC, that he's a chimpanzee...but with a tail. --- Darkness is overrated. We've been trying to tell mankind that since we started this absurd rebellion. The world-hater would say that darkness is easier to sell.
He did have a move called chimpy charge or something I believe, but he's not a chimp. If I had to guess, maybe a Brown Spider Monkey or Squirrel Monkey. --- "Do not expect to build up the weak by pulling down the strong." -Calvin Coolidge, 1914
^Agreed. Diddy is obviously a spider monkey. Now I wonder what some of the other Kongs are other than Donkey, who is obviously a gorilla. --- Must have: Legend of Zelda: Skyward Sword, Paper Mario, Donkey Kong Country Returns, and Kid Icarus: Uprising.
Now I wonder what some of the other Kongs are other than Donkey I think Kiddy and Chunky are supposed to be Baboons according to instruction booklets (that could explain the usage of clothing to cover their potentially red backsides) Lanky is an Orangutan Swanky and Funky are basically retooled Donkey Kongs, so more Gorillas at a guess
