The Monster's Monster by Patrick McDonnell

Three little monsters, Grouch, Grump, and Little Gloom 'n Doom are bad, bad, bad. But they can't decide who is the baddest of all, so instead they decide to build their own very monster. This monster will be the baddest ever. But to their surprise, he doesn't tramp through town and countryside terrorizing people. Instead, Monster is gentle and grateful, not at all what they were aiming for! McDonnell's delightful rhyme is a lesson in gratitude for little people -- and big people too. Illustrations and text seamlessly go together to make a truly delightful book for ages 3 to 6.

McDonnell is the author of the acclaimed comic strip, MUTTS and also author of numerous children's picture books. He began writing picture books in 2005, with the publication of his first book, The Gift of Nothing, which was a New York Times bestseller. This marked the beginning of some very engaging books which McDonnell has written since then.
