Through a voiceover, Sniffer (voiced by Don Knotts) introduces the five Air Buddies, describes their personalities and recaps how the puppies' father, Air Bud, made the town of Fernfield famous through his love of sport. When their families leave home for a basketball game, the puppies get into trouble with their sitter, Mrs. Niggles, by playing with balls of wool and eating a blueberry pie. This prompts their owners to finally put the puppies up for adoption.
