On Halloween night, a woman named Isabelle Peavy behaves rudely to the children in Punky's building and refuses to give them candy. Punky and Cherie enter her apartment to play a joke on her, but their plans go awry when Brandon accidentally left behind. The next day, Henry goes over to retrieve the dog, and he ends up learning some interesting information about Isabelle.
I actually remember watching this episode as a kid and enjoying it then. I like it even more, now. Oddly enough, it first aired after Halloween, in mid-November. But now I try and make a point to give it a viewing every year before All Hallow's Eve. Just reminds me of being a kid, it being too cold out to play, so I found myself watching some TV Programs that I dare say exceed the quality of much of what airs today.
