This was the last of the Annette Funicello and Frankie Avalon beach movies, but I have always especially enjoyed this one for several reasons. For one, Frankie Avalon and his hair helmet were only in the movie for seven minutes. (Although I am not sure that I liked his stand in, 'Dobie Gillis', any better.) Also, I really enjoyed Buster Keaton as a mad witch doctor, and Erik Von Zipper (Harvey Lembeck) got to sing two songs in the film. Annette Funicello does not wear a bathing suit in the film at any point becuase she was noticeably pregnant with her first child while the film was being shot.
