Pinky and Rex are excited. It's pumpkin-picking weekend with Pinky's Grandma and Grandpa. Pinky's sister and cousin are coming along, too. At Meadowbrook Farm, they'll pick the perfect pumpkin. Then they'll take it to Grandma and Grandpa's and carve it for Halloween.
But when Pinky's cousin arrives, she doesn't say hello to Rex. Instead she does her best to keep Rex out of the fun. Rex feels hurt. When a terrible thing happens, she feels even worse. How can she and Pinky be best friends again?
