Paratroopa (although commonly misrefered to as Parakoopa) is a driver in Mario Kart: Double Dash!!. His Special Item is three Red Shells. He has a red shell instead of a green shell, and has wings. His special item follows the racer in front of him, instead of bouncing off the walls. He is originally a partner of Koopa Troopa's, but you can mix him up with anybody else just as well. He has not featured in any other Mario Kart game.
Paratroopa was originally going to appear in Mario Kart Wii, but he was scrapped.
