Groovy Gustafer Yellowgold is a little, yellow, cone-headed fellow, who came to Earth from the Sun and has a knack for finding himself neck-deep in absurd situations as he explores his new life. His best friend is Forrest Applecrumbie, the world's last surviving pterodactyl, who staved off extinction with a sharp sense of fashion. Gustafer has a pet eel named Slim (short for Slimothy) and a menagerie of woodland creatures who curiously gather to share Gustafer’s solar warmth and quixotic sense of adventure. For recreation, he enjoys punching cheese and jumping on cake.
