Buster is a Hybrid creature that hails from a Mountainous region. This strange, roving beast may look imposing, but he's really a big softie! He's rather wild, so he can get rather rough. But he doesn't mean any harm. If you get him to cooperate, he makes for an effective Bodyguard! While he is capable of flight, he prefers to travel on foot. His favorite food is anything with Mint in it, he will follow you anywhere if you offer him any! Mint Cakes are his absolute favorite. The claws on his paws can be retracted at any time. He's careful with them, so they are almost always retracted by default.

He easily took a liking to Kiki, whom he considers a best friend. It is possible that he sensed the Kangaroo's fun-loving attitude, which suggests that he's emotionally drawn towards folks with a certain temperment! He's often called upon to assist her in her goals. Kiki designed and gave him a new collar as a present and symbol of their kinship. Buster in turn, gave her a new Handkerchief.
