Wracktail

Wracktail is a very powerful boss in the Wii video game Super Paper Mario. To beat him, you must use the same tactics you used on his younger sibling Fracktail in chapter 1. He is a skeleton dragon, and appears in the Pit of 100 Trials. Once you defeat this boss, you'll obtain Dashell, a Pixl that allows Mario and team to go super fast.

Wracktail and Fracktail are obvious references to Hooktail, Gloomtail and Bonetail from the previous game in ther series, Paper Mario: The Thousand-Year Door.
