My Amazing Dinosaur

The tribe knows that Tib's friend, Tumtum, is real. But not everyone loves the red dinosaur as much as Tib does. The other children aren't interested in playing with the creature, and they make fun of Tib more than ever. And some adults are still worried that Tumtum is dangerous. Tib's mother even forbids Tib from seeing his friend! How can Tib prove to the tribe that there's more to this dinosaur than meets the eye?
