The dinosaue who lost his roar

I read " the dinosaur who lost his roar" usborn first reading book, level three book.

the dinosaur has a big roar, and he always scares his friends withvhis voice.
But one day when he goes to scares his friends as usual
there are no one here.
What will he do??

I think that it was a very good story !
At first he used his loud roar to scares someone
but in imergency, he learned that his voice can use to help someone!
In fact, I think that he likes his friends,
and he want to proud of and enjoy them with his loud voice!
It was releaved that he is a very kind dinosaur!
