Koopa Troopas are Bowser’s main minions. While some are more pacifist, most are loyal to their King, bravely charging at Mario (and straight into a bottomless pit). After jumping on them, Mario can pick up and throw their shells at other enemies. Hit eight in a row for a 1-up! You can spot some in Smash on both the Mushroom Kingdom and Super Mario Maker stage, but they’re stuck in the background.
