Pinky and Rex love to play "monkey in the middle" with Pinky's little sister. But every time they do, their ball goes into Mrs. Morgan's yard. And every time it does, she flies out the door and screams at them. She even tries to hit Rex with a broom! Now the kids want to get even with the Mean Old Witch of Elm Street. But when Pinky creeps up onto Mrs. Morgan's front porch, he sees her sitting alone in a dark house and decides that revenge is not...

Although his best friend Rex is excited about going to camp, Pinky is afraid of leaving home.

Pinky and Rex share a weekend with their fathers camping indoors due to rain.
