Billy Chicken is a chicken who is also the mayor of Silly Town. He showed Steve (and later Josh) around the place and its mixed-up people and places, including a construction site and its wacky workers, the center of town where the vehicles make strange sounds, and Backwards Park (where everyone and everything moves backwards).
Billy Chicken is the mayor of Silly Town, where everything is silly. He travels in a giant egg when not walking forwards (or backward).
He is featured in "What's So Funny?" and makes cameo appearances in "Magenta Gets Glasses", "What's New, Blue?", "100th Episode Celebration", and "Dress Up Day". He returns in "Laugh with Blue" in "Blue's Clues & You!".
- After Sock Puppet told his joke about "why did the sock cross the road" in 100th Episode Celebration, Billy Chicken popped up from behind Steve's left shoulder.
- In Blue's Clues & You!, he is voiced by Cory Doran.
