Charles is one of the characters from Timothy Goes to School. He is a friendly but very withdrawn mouse. Due to being so shy, he sometimes struggles when it comes to approaching others or speaking up, until he gets to know them. He enjoys typical boy activities, such as pretending to be an astronaut or a plane flyer. He doesn't really seem to like sports as much as the other boys though, and when he gets to know someone, he can be very kind and sweet to them. He also like to play by himself at recess.
