The Tritonian Yeti has only 1 appearance in Futurama. In "The Tip of the Zoidberg" Hubert J. Farnsworth acts like a Yeti, to kill whatever it finds. John A. Zoidberg gets attacked by the Tritonian Yeti. Professor Farnsworth attacks the Tritonian Yeti with a knife and gets scratched by the Yeti. In the present Professor Farnsworth thought he had Hypermalaria but instead it was Yetism which mimics the symptoms of Hypermalaria but instead of dying one become a Yeti. The symptoms of Hypermalaria are fever, spasms, madness, coma, and finally death.
