Shady Koopa

A Shady Koopa is a Koopa Troopa with a blue shell and slightly darker skin coloration. They appear in Paper Mario: The Thousand-Year Door, first as one of Mario's opponents in the Glitz Pit, along with a Shady Paratroopa and second in the Pit of 100 Trials. They can attack even when turned on their shell. Contrary to what Goombella and the Tattle Log say, their attack does not increase when they get back up. However, their back-attack hits both Mario and his partner and has a power of 6, which is double their normal attack.

Trivia

 * If Mario manages to perform the B-Action command on a Shady Koopa when they use their unique Power Shell technique when they are flipped, the Shady Koopa will walk backwards on his feet for a slight second and then return to his state being flipped on his back.
