Kabu is a dwarf from Tontatta Kingdom who first appeared on Green Bit, when the Marines were attacked by dwarves. He is the one who got caught by Robin during the Green Bit exploration.

Kabu, like all the other dwarves, is small and has a large fluffy tail and a pointy nose. He appears to be older and chubbier than the other dwarves. He also has a lot of facial hair. He sports a dark coat, with a double breasted button up shirt, and scarf.
