Donna tries to redecorate the house, but neighbor boy Dennis Mitchell (Jay North) tries to help her...and ends up making things more of a mess. Donna finally calls Dennis' nearer neighbor Mr.Wilson (Joseph Kearns) to ask if Dennis would help him with anything. (I'm sure Mr.Wilson sympathized.) This was a crossover show-with two people from ""Dennis the Menace"" guesting. It turns out both shows are set in the town of Hilldale...but Dennis probably lived in a different neighborhood than Donna. (thetvdb.com)
