Little House on the Prairie (1974)

S6E14 The Werewolf Of Walnut Grove

Bart, the school bully, starts to torment his fellow students, particularly targeting Albert. Frustrated by the relentless bullying, Albert crafts a paper maché werewolf mask to scare Bart into backing off. The plan initially succeeds, but things take a turn when Carrie inadvertently ruins the effect with her comments. It ultimately requires a united front from all of Bart's classmates to put an end to his bullying once and for all.
