Pilot a Blimp
In the Casino City, you'll see a blimp flying around. Wait for it to land and when the back hatch opens, drive in. It closes and takes off. You can steer it, but can't go up and down. If you're flying over a building with cool power-ups, push Accelerate and you fall out. Watch out because if one of you opponents has heat-seekers or something and they shoot it, it will hit the blimp and the blimp will explode and you don't get it back.
