This animated series is based on Marc Brown's best-selling books about Arthur Read, an eight-year-old aardvark, his sister D.W., and their family and friends. Arthur wants to prove to his parents that he's responsible, but gets more than he bargained for when opening "Arthur's Pet Business." Arthur is upset that D.W. doesn't share his tastes, but in "D.W. the Copycat," he finds that sometimes that's for the best.
