Three Mayonnasians (and their dog) make their way to Sesame Street, curious as to how their entire planet feels a lack of energy throughout the morning. They learn about the concept of "breakfast," which pleases them, except their planet lacks the flora and fauna to produce breakfast. Throughout the show, Big Bird, Gina and others provide them with the necessary resources, which they beam into their spaceship and return home. The planet was later mentioned by Big Bird in episode 4037, as he pretends to be a superhero.
