Bones

Bones was the clumsy companion of Donkey Kong Jr. throughout the Donkey Kong Jr. segment of Saturday Supercade.

Summary
As the story goes, Bones had found Donkey Kong Jr. depressed on the street; it seems Junior had traveled from unknown location in order to visit his father, Donkey Kong. Unfortunately for Junior, Donkey Kong had run away from the circus he was at, with Mario and Pauline on his trail.

Bones decided to aid Donkey Kong Jr. in his search for his father, and off the two went across the country on Bones' motorcycle, going on various misadventures during their search.
