So basically here's something I imagine for The Backyardigans if it had a sixth main character. I had an idea to make the sixth character a cat named Felix. He has (almost) black fur with white (or light periwinkle) on his muzzle, belly, and the tip of his tail. He has a pink nose and wears a red shirt with a yellow star on it and bright green pants. In the 1998 pilot, his nose is black, his shirt is purple instead of red, and his pants are teal. His house is on the very right side of the backyard, next to Austin's house. It's a black house with 4 visible windows, 2 on the roof. He is the potential neighbor and best friend of Austin. He is very mischievous and enjoys doing funny, crazy and wacky things that often make the others laugh. Oh, and by the way, I did have The Backyardigans Movie (and Super Why: The Movie) in mind, and still do. But I have something else in mind now too. It will be an at least one hour long special episode titled "The Backyardigans: The Wizard of Oz". It will have the plot of the well known "The Wizard of Oz" with The Backyardigans, and Felix, taking the roles. The roles I have in mind go as follows: Uniqua as Doreeniqua (equivalent of Dorothy), Pablo as the Scarecrow, Tyrone as the Tin Man/Robot and the Wicked Witch of the East, Tasha as the Wicked Witch of the West, Austin as the Cowardly Lion, Ziggy (another OC I have) as Doreeniqua's dog (equivalent of Toto), and Felix as the Wizard of Oz!
C2A The Backyardigans belongs to Nelvana, Nickelodeon, Treehouse TV, and Paramount.
