Happy Tree Friends (commonly abbreviated as HTF) is an adult animated web series created by Aubrey Ankrum, Rhode Montijo, and Kenn Navarro, and developed by Montijo, Navarro, and Warren Graff for Mondo Media. Disguised as a children's cartoon, the series follows the misadventures of cute anthropomorphic forest animals, who live initially peaceful lives until they are killed or injured in sudden, usually accidental, graphically violent incidents. Debuting sometime in 2000, Happy Tree Friends has achieved a cult following on Mondo's website and YouTube channel and expanded into a multimedia franchise, which includes the television series of the same name.
