Koopa Paratroopa
Koopa Paratroopas are a species of Koopa Troopa that appear in a few Yoshi games, but originate from the Mario games. They can be attacked like normal Koopas, but they can fly. If Yoshi or his allies do a jump on it, they will lose the wings they have. As said in one game, Paratroopas without wings are very sad Koopas. Red shell Koopas fly back and forth, and the green ones jump to the player. They appear in Super Mario World 2: Yoshi's Island, and Yoshi's Island DS. Green Koopa Troopas always jump until they bounce off a wall or jump into a ditch. Red Koopa Troopas are smarter though, as they turn back the other way when they reach the edge of an abyss.
