Fifth entry in the "Beach Party" series (after "Pajama Party") is by far the best and has achieved near-cult status. Both Funicello and Avalon are back, but this time a very young Evans catches Avalon's eye. Throw in a mermaid, some moon-doggies, skydiving, sizzling beach parties, and plenty of nostalgic golly-gee-whiz fun and you have the classic '60s beach movie. Totally implausible, but that's half the fun when the sun-worshipping teens become involved in a kidnapping and occasionally break into song. Followed by "How to Stuff a Wild Bikini."
