Un problema espinoso

Tracy and Stella Stegosaurus can't stop arguing. Tracy bumped into Stella, and Stella took Tracy's lunch spot. Then Stella said dinosaurs with bumps on their backs should be best friends, which leaves Tracy out. When things boil over, the Dino Crew steps in to help them figure out how to get along.
