Lice have invaded school… and the Zlipper brothers’ heads. Gracie gives them shock treatment in an extended bath session with Buggykill shampoo and warns them that if she finds another louse, they’ll have to get their heads shaved! Zip and Zap are sure that it’s all the girls’ fault for having long hair, and swear to steer clear of them, but Evilina and Wanda are not willing to take the blame for the other guys’ lice, so for the first time they band together for The Lice Wars! Or, better said, the Battle of the Sexes! Will the boys win? How long will Wanda and Evilina’s “partnership” last?
