Kart

Karts are seen in CTR and CNK. In CTR, each character has a specific colour for their kart. (Ex. Tiny is green).

In CNK, they are blue for Team Bandicoot, red for Team Cortex, green for Team Trance and yellow for Team Oxide. They are like basic go-karts, except that they are faster and can fire different weapons like missiles or bombs.
