Finlay (a little dinosaur) is counting out jelly beans to share with his friend.

He is sitting on a grassy mound. A big dinosaur comes along and demands the jelly beans.

He is rather rude, a bit of a show-off, and he thinks that Finlay's friend is a figment of his imagination.

What follows is a lot of posturing from the big dinosaur as he attempts to prove his worth with various antics on and around the grassy mound.

As the book progresses it will gradually become clear to thereader that the 'grassy mound' is in fact, Finlay's friend, the really, really, really big dinosaur!

The big dinosaur certainly doesn't realize until his bravado propels him into a dark cave that turns out to be the mouth of the really, really, really big dinosaur.

It's only then that the big dinosaurlearns that in order to make friends it's a good idea not to show off and it's a good idea to be prepared to share.
