In the last beach party movie to feature Frankie Avalon and Annette Funicello, he’s deployed in the navy and worried about her faithfulness back on the California beaches. To make sure that no guys tempt her, he has an island witch doctor send a sea witch, Cassandra, to attract the attention of a handsome ad executive. But, the plan backfires when everyone on the beach falls under Cassandra’s spell.
The soundtrack is filled with plenty of dance numbers and swinging beach music songs like The Kingsmen’s Give Her Lovin’. How to Stuff a Wild Bikini is innocent fare compared to later beach movies, but engagingly trippy and fun.
