Be my Hero!!

There is a book I ran across online a few weeks ago… it was a favorite of mine when I was a child. I saw the cover, gasped at the memory of it, decided I had to find a copy for Will… and then got distracted and it was gone.

All I can remember is that the book had something to do with a boy and his pet?friend? dinosaur?monster?something? It is draw in a realistic cartoon-y style (not unlike Judith Viorst, but maybe with a little Mo Willems influence.) One thing I remember about the book is that the monster?dinosaur?thing? is very big — there is one part in the book where you have to turn the page to see the rest of it’s body.

It is driving me batty — I can’t remember it!! Can anyone help????
