Did you know?

Apatosaurus was a giant dinosaur that could grow up to 23 meters (75 feet) long! It took several years to grow that big. You might also hear it called Brontosaurus, but they're actually two different dinosaurs.

Katia wrote ten “did you know” facts for the end of Dinosaurs Are Back, one for each dinosaur Spike meets. This is the Apatosaurus one, and the film next to it reads it aloud.

In the story

Spike meets the Apatosaurus

He had big red eyes that looked really sad. He said he'd help us, but only if we found the mysterious "fruit of euphoria".

It turned out to be a very ordinary pineapple. I've never seen a dinosaur laugh so hard.
