Miscellaneous
A kart frame named Bullet Duck was mentioned on several websites but was not seen in the game. Also, a kart called Banana Buggy was mentioned; this was likely an early name for the Bolt Buggy, which is in fact called Banana Buggy or something similar in many languages other than English. The Streamliner was mentioned due to a recognition mistake; it was actually the Blue Seven.
