In an acting stretch, Frankie Avalon here plays both his usual surfing namesake and a vacationing mop-top English singer named the Potato Bug (the sort of British invader that sank Avalon's recording career), who becomes Frankie's rival for Dee Dee (Annette Funicello). The sandy turf is

also threatened by wealthy curmudgeon Harvey Huntington Honeywagon (Keenan Wynn), who wants to evict the surfers from the beach to build a senior citizens' community and who endeavors to prove that his chimp is smarter than American teenagers. Eric Von Zipper (Harvey Lembeck) is HHH's

not-so-unlikely ally and Don Rickles' is teen sympathizer Big Drag. Little Stevie Wonder, the Pyramids, and the Exciters add some much-needed life to the proceedings, and Boris Karloff has an uncredited cameo.
