That's a KP Koopa. It's a Koopa Troopa of a slightly different color. Max HP is 4, Attack is 2, and Defense is 1. Looks like its abilities are just like any Koopa... So he oughta be a piece of cake! Don't go easy just because you know King K, Mario... That's what friends are for!
A Koopa warrior that battles at the Glitz Pit in Glitzville. It may be a different color than your average Koopa Troopa, but its abilities are the same.
