"Sassy and Waldo love to have fun! Like when they put on their trench coat and everyone thinks they're a student named Salty. Stewart knows the truth though. He is their best boy. Their whole class is doing a school play. Play? Dogs love to play! But now Stewart is acting like a different person. An evil person. Sassy and Waldo need to get their boy back! Even if it means doing that other kind of play."--
