Koopa Troopa

A Koopa Troopa is a henchman of Bowser. Koopa Troopas are hostile towards Mario, Luigi, Peach, Yoshi, and  Toad and will attack them. Unlike the Koopa Troopas seen in the Mario games, they don't go into their shell and attack Mario characters like a normal human. Green and Red ones appear randomly each time you type in the object.
