Shady Koopa

A Shady Koopa is a Koopa Troopa with a blue shell and slightly darker coloration of skin. They appear in Paper Mario: The Thousand-Year Door, firstly as one of Mario's opponents in the Glitz Pit, along with a Shady Paratroopa and secondly in the Pit of 100 Trials. They can attack even when turned on their shell. Their back-attack hits both Mario and his partner, and has a power of 6 - which is double their normal attack.
