He lives with his sister Betsy, dog Charkie, & Aunt Margaret in the City. He's always "going for a record" of some kind. He's selfish, & clearly has a high opinion of himself. He feels grown-up though his sister often corrects & outsmarts him. He has more responsibility, which is seen in many Steve & Betsy encounters. Most times when he hangs out with George, he always gets to some short of trouble. One time he tried to get a honeycomb back, but instead he made a beehive, in which that time, turned out okay. (Honey of a Monkey) Another time he was playing with George's Bouncy-Yo, & ruined Betsy's pictures. (Shutter Monkey)
