Choco Mountain is the 3rd track in the Flower Cup in Mario Kart 64. It is brown, and as the name suggests, it is probably chocolate. It features a chocolate tunnel shaped like a pyramid, and at one point, big chocolate boulders crash down onto the track. If a player is hit by these boulders, it'll knock them off the track. A bit before the start line, there's a point where the players can fall to a lower section of the track, losing about 20 seconds. In 50cc mode as well as Time Trials, There are railing along the cliff which prevents you from falling. Meanwhile, in 100cc and 150cc, there is no railing, which makes it possible to fall, or knock someone off it.
This track returns in Mario Kart DS. The track is still pretty much the same from the N64 version, except, if a player/computer gets hit by a boulder here, he/she will be flattened, thus slowing them down. In Mission 4-6, Donkey Kong has to destroy 10 item boxes while avoiding the fake item boxes. The staff ghost uses Wario in the Dragonfly.
