The Beach Party gang is back in this third episode. This time out, the gang is visited by the handsome British pop star Potato Bug (Frankie Avalon in a dual role) who has come to CA for a little r&r. When Potato Bug sees the perky Dee Dee (Annette Funicello), he falls head over heels. This doesn't set well with her boyfriend, Frankie. Later the kids all join forces to keep aged developer Harvey Huntington Honeywagon from buying their beach and using it to build a senior citizen's resort. Honeywagon is assisted by Brandoesque biker Eric Von Zipper while the kids are helped out by the adolescent supporter Big Drag. Songs include: "Bikini Drag", "Love's a Secret Weapon", and "Because You're You". Special guest artists include Little Stevie Wonder, the Exciters and the Pyramids. Boris Karloff has an un-credited cameo.
