Bronto's Big Adventure

Bronto, a young Brontosaurus, wants to go on an adventure all on his own. He thinks he's big enough. He doesn't need his mother to protect him. But it's a big, dangerous world out there, especially for such a small dinosaur.

What mischief will Bronto get into? Will he be okay all by himself? Or will he realize that he needs the help and protection of others?
