The Tritonian Yeti has only one appearance in Futurama. In "The Tip of the Zoidberg", Professor Farnsworth acts like a Yeti, by killing whatever it finds. After Dr. Zoidberg is attacked by the Tritonian Yeti, Farnsworth fights off the creature with a knife and gets scratched by it. In the present, Professor Farnsworth thought he had Hypermalaria. However, it was Yetiism, which mimics the symptoms of Hypermalaria but with the victim acting like a Yeti instead. The symptoms of Hypermalaria are fever, spasms, madness, coma, and finally death.
