The Taco Bell Killer works at a Taco Bell in the woods. He was dressed in black. He had a Taco Bell logo sewn on the left of his fleece jacket. He was wearing squeaky shoes, that squeaked across the floor, and was wearing dark sunglasses. He was also the man who murdered Dipper and Mable Pines and puts their remains in a plastic bag, which he later uses to make tacos with the help of an unknown machine.
