A three-year-old boy named, Casen was about to have a once-in-a-lifetime birthday moment. Casen loves dinosaurs, and his parents decided to have a ‘Three-Rex’ party in his honor. There was a dinosaur cake and theming throughout the home. However, nothing could compare to what happened outside. Walking right down the sidewalk is an awesome T-Rex puppet with a handler. Casen believes these are real dinosaurs who have come to his party to celebrate with him.
