Spaghetti

Spaghetti is a dog created by Carl with the "Make Your Own Dog 1.0" software in the episode "Hand Banana." Carl wanted to call him "The Enforcer," but he instead wanted to be named "Spaghetti." He has the same voice as Carl, along with the same sandals, tan lines, hair, and gold chain because of Carl's DNA.

Spaghetti rapes Carl after he claims to "feel a connection" after seeing they have the same hair growth pattern. The episode ends with Master Shake watching his neighbor get sodomized by the human-dog hybrid (disturbingly, masturbating to it), assisted by Hand Banana. Frylock tells Shake to go in his room "If thats what he's going to do." Master Shake then angrily replies "I don't have a room!"
