Koopa Shell

Koopa Shells are the turtle shells worn by Koopa Troopas. They have hexagon-shaped scales and a beige-yellow border. They can be used as weapon when kicked by Mario or his friends, and they can have different effects depending on the variety. In some games, the Koopa stays inside of the shell when it retreats and will reappear, while in others it pops out of the shell and becomes a Beach Koopa.
