"Huck is terrified when he first sees the stegosaurus. He goes as quickly as he can to Chief Whitewater to tell him there is a monster someone needs to kill. Of course, the chief doesn’t believe him. So, the next time Huck goes to the spring to wash clothes, he takes his grandfather’s gun with him. 

Before Huck can shoot the dinosaur, he learns that George is friendly, and he also learns that the two children, Joey and Joan, already know George. Huck goes to the resort to swim with them, and they go fishing with Huck. They take George with them and introduce him to picnics. He likes the food and loves Indian wrestling, which Huck teaches them all. It’s great fun for George because he wins every time."
