Nabbit

Nabbit is an underhanded thieving rascal of a purple rabbit with a sack of stolen goodies slung over his shoulder and a pair of speedy legs for getaways. He might have buckteeth, but prefers to draw sharp teeth on a bandana to look scarier. He resides in the Purple Toad House on the secluded Secret Island in the Mushroom Kingdom, where he keeps up to date records about Mario and friends, whom he seems to be keeping a close eye on. It's a little hard to classify him as an ally or an enemy of Mario; you'd think Nabbit's habits of stealing from Toad Houses would put him at odds with the good guys, but he seems content to join and help them on other occasions. His "enemies" seem to just be whoever has something he wants to steal.
