Little Bill's imagination wanders to the planet BleeBlop, where he is just the right size to help Captain Brainstorm (voice of Bill Cosby) save the day for several giant purple aliens. It's a stark contrast to planet Earth, where it seems Little Bill is "too little" to do much of anything. Other voices include...Brenda: Phylicia Rashad. Big Bill: Gregory Hines. Max: Robert Scull.
