Found within the game's data is an unused Red Koopa Troopa that can only appear through hacking methods. Unlike the green Koopa Troopas found in the game, the red ones will attempt to run at the player and knock them around similar to Bullies. When knocked out of their shells, they'll slowly walk back into them instead of panicking like the green ones do. In addition, their shells cannot be ridden. Instead, they will only slide along the ground like in previous Mario games, killing enemies in their path until they break against a wall. If a Red Koopa Troopa is eaten by Yoshi, he'll spew out fire like he does when eating one in Super Mario World.
