Another couple of villains show up in the sequel wanting to make Buddy work in their circus and Buddy gets kidnapped again. It is the same boy in the movie, but now he is a little older and upset about his mother dating a new guy. This guy buys Josh a football and they find out that Buddy is excellent at another sport. Buddy joins the football team with Josh - because the township still hasn't made a rule against animals who don't attend the school playing for the team.
It was a pretty good sequel, and the only other Air Bud movie that actually played in theaters. We were inspired to play football while down the shore this weekend.
