Tiny Titan
The Rally Romper (known as the Tiny Titan in North America) is a small kart that appears in the game Mario Kart Wii. It is based on the Monster from Famicorn Grand Prix II: 3D Hot Rally. The Rally Romper is unlocked by unlocking one expert staff ghost or by winning 50 races online.

Despite its apperance, the Rally Romper's weight is nowhere near the weight of a large vehicle, though it is the heaviest among all of the small vehicles in the game. At best, this kart's weight can only surpass the weight of the Super Blooper and all of the medium bikes (except Dolphin Dasher), but only if the babies ride on it (Baby Mario, Baby Luigi, Baby Peach and Baby Daisy). This vehicle is a Rally type vehicle, hence the name.
