Join Arthur, possibly the world's most famous eight-year-old aardvark, his sisters DW and Kate, and their friends Buster, Francine, the Brain, Muffy, Sue Ellen, Fern, Prunella and Binky as they encounter the joys and difficulties that all children experience in their adventures through life. Based on the popular children's books by Marc Brown. Binky's baby sister, Mei-Lin, is not all that keen on learning to walk, and would rather stick to crawling. But then Baby Kate and Pal's flea friends, brothers Pepe and Sale, return to Elwood City with a tale of a little princess in the land of Hanzan-Niis who learns to walk in order to save her beloved court jester. Will Mei-Lin be inspired to take a stand, or will she continue to stumble?
