Sequel to "Beach Party" finds Frankie and Annette romping in the sand again. Trouble invades teen nirvana when a new gym opens and the hardbodies try to muscle in on surfer turf. Meanwhile, Paluzzi tries to muscle in on Funicello's turf. Good clean corny fun, with the usual lack of script and plot. Lorre appeals in a cameo, his final screen appearance. Watch for "Little" Stevie Wonder in his debut. Rickles' first appearance in the "BP" series; Lupus was credited as Rock Stevens. Followed by "Bikini Beach."
