The Monster's Monster by Patrick McDonnell
Little, Brown Books for Young Readers, September 4th, 2012
Grouch, Grump, and little Gloom 'n' Doom may think they're terrifying monsters, but it must be said that they all look a little cute. Determined to be the baddest of the bad, they build the biggest baddest monster ever, a monster whose first words are..."Dank you!" accompanied by a hug. Whatever will Grouch, Grump, and Gloom 'n' Doom do? Caldecott honor-winner Patrick McDonnell's spirited illustrations will charm readers. A great pick for your own monsters-- whether or not they're the biggest and baddest.
