Dad has warned Henry and Eve: If you whine too much, monsters will eat you. Henry and Eve don’t listen, of course. The only problem is, when the monster comes, he can’t find the right recipe for whiny children—and neither can his monster friends! A whiny child salad doesn’t work because there’s paprika in the dressing. A whiny child cake won’t do because the flour spills all over the floor. And whiny child burgers are out of the question because the grill is too hard to light up. Arguments and hilarity ensue. And just when our persnickety monsters decide on the perfect dish…the worst thing of all happens….

Henry and Eve are two perfectly delightful children. A brother and a sister. They have one little fight. It's not the end of the world. Or is it?
