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. On "Arthur's Family Vacation," things get off to a rocky start, but the family makes the best of some tough situations. In "Grandpa Dave's Old Country Farm," Grandpa is too proud to accept some much-needed help in keeping up his farm, until the kids come for a visit and show him how badly the repairs are needed.
