Carbuncle

Carbuncle is the happy go lucky mascot of the Puyo Puyo series, and Arle Nadja's travelling companion, best friend and sidekick.

Appearance
Carbuncle is a small, yellow rabbit-like creature with a red gem on his head (hence his name) and a big smile.

History
Carbuncle was originally the pet of Satan, but upon Arle Nadja defeating Satan in battle, she stumbled across the creature. The gem in Carbuncle's forehead is said to contain mystical magical powers. Rather than taking the gem for her own, Arle simply befriended Carbuncle and the two have been almost inseperable since.
