Muskox's are on 3 different episodes, and are #5 on Fighters, #5 on Stinkers, and #9 on Athletes. Unlike their name suggest, they don't produce musk, and they are not an Ox. Males fight each other by crashing their heads together. They can run at 50 kilometers per hour, head first into the other males head. They have very thick bones on their horn, to protect their skull. They also douse themselves in pee to see who can make the biggest stink. If you stand down wind, the smell is enough to make your eyes water.
