Loonette the Clown
Loonette the Clown is the lead character, portrayed by Alyson Court from 1992-2002 and Ramona Gilmour-Darling from 2006 onward. 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. In the episode "going up" she was briefly a giant but it's possible she actually loves being a giant shaking the ground with her huge feet. She also secretly loves how big she wants to be especially her feet.
