Darlie is one of Clarence's classmates in Ms. Baker's fourth grade class. She is often seen in the background during Clarence's adventures, but has yet to make a significant appearance.
In the "Pilot", Darlie wears a long red hoodie and white boots. Though the hood covers most of her head, you can see her blonde bangs in the front.
For the remainder of the series, Darlie is redesigned and wears a long blue hoodie with a huge zipper in the front. Her hair is now brunette and she wears blue boots.
