Trivia

 * Green Baron's original name was Crimson Baron.
 * Foreman Pig's karts look like planes rather than karts.
 * On Matilda's track, it is possible to access a shortcut in Versus Mode if you fly over the barrier, and manage to push against the force trying to push you back on the track.
 * On Foreman Pig's track, it is possible to enter the lower tunnel in the 3-way shortcut part of the track, but only if your kart is badly damaged and get enough speed to get to the lower tunnel where there are no TNTs or coins.
 * Foreman Pig's kart, the High Flyer, can regain it's wings by just reviving (to revive, get a high amount of damage or slow down or bump to the edges).
