This little dinosaur is on a MISSION - a mission to find a T-Rex. All the other little dinosaurs are a little bit scared, but our little dinosaur sets out to meet one and on the way, asks everyone, Excuse me, are you a T-Rex? No one we're introduced to is a T-Rex, but we do get to meet a chindesaurus, a plateosaurus, a stegasaurus, a bracheosaurus, a diplodocus, a bactrosaurus, a hadrosaurus, a velociraptor (eek!), a triceratops, an argentinasaurus, an ankylosaurs and - eventually - a T-Rex!
