Bonetail

Bonetail is a large zombified Dragon, living at the bottom of the Pit of 100 Trials.

He is the oldest member of the "tail" family, older than both Gloomtail and Hooktail. As his name implies, he is merely a skeleton of a Dragon, implying that he has been living far longer than the other members of the family. The reason why he became a skeleton is that he never ate anything for so long and died of old age. He was once a minion of Shadow Queen, but has apparently stopped serving her. Any actions outside of the Pit of 100 Trials, if any, are unknown.

After Mario and his teammates reach the bottom floor of the Pit of 100 Trials and defeat him, they'll earn the Return Postage Badge.

Only appearance: Paper Mario: The Thousand-Year Door

Stats and Tattle Information (Paper Mario: The Thousand Year Door)
HP: 200, Attack: 8, Defense: 2

Tattle: That's Bonetail. He's the oldest brother of Hooktail. ...So old he's just bones, in fact. Wow. Now THAT'S old. His body's Max HP is 200, his Attack is 8, and his Defense is 2. He has various breaths that might confuse us or put us to sleep. When his HP gets low, he'll recover... or reanimate, as the case may be. He's probably stronger than the last boss, seriously! Let's do this right!
