The Happy Helmet is a Stimpy's inventions. It is a gray helmet with a yellow annetenae that allows it to be used with a remote control. Its function consists to force the unhappy person wearing it to be in a state of happiness and bliss against their will. As shown by Ren Höek, it forced him to be kind to Stimpy, doing several of his chores, between that iron his underwear and clean his dirty litter box. It also forced Ren to put happy stickers in his bedroom and dance to "Happy Happy Joy Joy", to the beat of whose music Ren rapidly banged his head with a hammer, effectively breaking the helmet and its hold over him once and for all.
