Loonette is the lead character, portrayed by Alyson Court. She is a young clown living with her dolly, Molly, on the eponymous Big Comfy Couch, an over-sized couch.
She frequently reads stories to Molly, always performs a Clock Rug Stretch, and likes to visit her Granny Garbanzo. Auntie Macassar (or more recently, her Uncle Chester) frequently sends Loonette postcards which Major Bedhead delivers on his unicycle (similar to Reba the Mail Lady from Pee-wee's Playhouse). Her Parents are never seen or mentioned. Loonette is gifted in the art of classical dance and runs "Miss Loonette's Dance Academy". Another gift she possesses is the unusual ability to clean just about any mess up in ten seconds, which she calls the "Ten Second Tidy". (In reality, the video's action was sped up during post-production of an episode).
Originally, Loonette was too young to visit Clowntown, but starting from 2006, Loonette makes frequent (adult supervised) trips to Clowntown to visit Granny Garbanzo's "Cabbage Club Cooking School" and Major Bedhead's "Clown Chi Mojo Dojo and Dancing School". The trips to this second location indicates that she practices martial arts.
