Taury, Patsy, Sid and Trike, Pterence, Steggy, what a sight! Harry and his dinosaurs are quite a team, but now one of their own, Steggy, has gone missing! Harry's worried that he may have left him at Magic Land, an amusement park he visited with Sam and his Mom. Sam won a giant elephant-toy after playing all the games at the park, but Harry didn't win anything and now he's down one dinosaur. Steggy definitely isn't in the bucket and a thorough search of the car and Harry's belonging's comes up empty as well. Harry and the dinosaurs realize that ther'e somewhere else they might find Steggy - in Dino World. They all hop into a bucket and find themselves in an amusement park similar to Magic Land. They search everywhere, even a scary haunted house, but come empty. All their searching, however, leads to a surprising idea as to just where Steggy might be.
