The Two-Headed Monster is, as the name implies, a monster with two heads. He speaks gibberish that resembles baby talk, and many of his skits have to do with either cooperation or sounding out parts of words that suddenly show up. Skits with the Two-Headed Monster usually take place with the monster behind a brick wall, and in at least one instance, with his mother.
The creation of this monster was inspired by performers Jerry Nelson and Richard Hunt playing around on the set one day, saying that they were a monster with two heads. While right-handed performers use their right hands to perform the heads of characters and their left to perform left hands, whoever performs the left half of the monster performs the head with the left hand, and the right hand with their right hand.
Although the heads don't normally go by names, they have been identified on occasion. In a Sesame Street sketch, Olivia reads a story to the Count about cooperation. It stars the Two-Headed Monster named Horn and Hardart. In The Sesame Street Treasury Volume 13, the pair are featured in a photo answering phones. Their phones are labeled "Frank N." and "Stein" (Frankenstein).

|Ernie:||Yeah, but, Bert, he said he'd never been in a play before... I mean they said it... um... both of him said it.|

| || Cooperation |
| The Count listens to Olivia read the story, "The Two Headed Monster", enacted by the titular monster. The book is about how the monster cannot decide on what to do because both heads want to do different things. Eventually they learn that together, they are able to lift weights, play doctor ("Kildaire! Kildaire!"), play the piano ("Tchaikovsky! Mozart!"), and eat a salami-and-cheese sandwich.
In this sketch, the actual names of the monster are revealed to be "Horn" and "Hardart". The monster also has different perfomers. Instead, Richard Hunt plays the left half, while the right half is performed by Peter Friedman. This was presumably done so that Jerry Nelson could play the Count live to the Two-Headed Monster's reactions.
