Once upon a time, there were three little rascals who thought they were the BIGGEST, BADDEST monsters around. But when they decide to build a huge monster of their own, he isn't exactly what the creatures were expecting. He's happy. He giggles. He's just grateful to be alive. And he has a lesson for his grouchy creators that only takes two little words.

In this playful tale from bestselling picture book author Patrick McDonnell, a very BIG monster shows three very BAD little monsters the power of boundless gratitude.
