ARTHUR is based on the best-selling children's books by Marc Brown. The series revolves around an eight year-old aardvark, his four year-old sister DW, and their family and friends. ARTHUR is a show about being a kid, exploring the world, and finding your place in it. It's about kids finding inner strengths, learning to make choices for themselves, taking responsibility for them and of course, having fun. In each episode, Arthur and his gang guide us through stories that deal with real "kid issues" -- timeless difficulties and joys that all kids experience. The series also models the joys and rewards of literacy by presenting the many ways kids and adults incorporate reading and writing into their lives. Above all, ARTHUR is a comedy that tells its stories from a kids' point of view, never moralizing or talking down to them.
