Everyone knows that gangs have terrific fun! So Steve, Debbie, and Howie decide to start their own. They invent a password to keep it really special and secret, but the only person who can remember it is Debbie’s four-year-old sister Bet. And who ever heard of a gang with a baby sister?
Buster, the next member to join, has four legs, a long tail, and a cold wet nose! Nothing daunted, the Gumby Gang set out on a series of hilarious adventures that always seem to go a bit wrong.
