Spiked Koopa

Spiked Koopa Troopa is a boss in Super Mario Land 3: Wario Land. He resides at the end of the Rice Beach stage. As his name implies, he is a massive Koopa Troopa with a spiked shell on his back, and another one on his head. In his fight with Wario, he employed a three-pronged attack of striking from land, air, and underground. His shell makes him invulnerable to ground pounds and fire.
