What is the name of the biker gang in "How to Stuff a Wild Bikini"?

Having spent a great deal of his adult life in uniform, Lembeck once again donned Navy togs in the 1962-1963 season to co-star with Dean Jones in the NBC sitcom Ensign O'Toole. He co-starred with Steve McQueen in Love with the Proper Stranger and then spent part of the early 1960s playing the lovable bad guy Eric Von Zipper in seven American International Beach Party films, with Frankie Avalon and Annette Funicello. (He did not appear in the second "beach" film, 1964's Muscle Beach Party.) The Von Zipper character, leader of the Rat Pack motorcycle gang, was a parody of Marlon Brando's role in The Wild One.
