Fluffy

In the film "The Crate" from Creepshow, a janitor discovers a man-eating Arctic monster named Fluffy in a mysterious crate at a university. Fluffy escapes, wreaking havoc and devouring people. Eventually, Fluffy is contained again and dumped into a quarry lake, seemingly defeated. However, Fluffy survives and breaks free to continue its rampage. Fluffy never attempts to leave its crate and only attacks in self-defense, resembling the cryptid Yeti. The origins of Fluffy and its motives remain a mystery.
