Tiny Tug

The Tiny Tug is a kart part that players can unlock in Mario Kart 7. This kart part is shaped like a boat, even having a pipe that spouts orange-colored steam when doing certain actions. It offers a weight boost, and an off-road boost; however, it hinders speed. It is one of the only five karts to increase off-road boost, with the other four being the Bolt Buggy, Bumble V, Cact-X, and Pipe Frame.

Of course, while the Tiny Tug does have one of the lowest speed stats in the game, it's one of the best kart bodies when it comes to underwater performance, having the best sea speed (tied with the Egg 1) and sea handling (tied with the Cloud 9) of all kart bodies.
