We love the book "Goodnight Goon." It's a spoof of the classic children's book "Goodnight Moon" so most kids are familiar with the story line, but instead of saying goodnight to the cows jumping over the moon, you say goodnight to the "martians taking over the moon." And there is a "hat and a shoe and a pot full of goo and a hairy old werewolf whispering boo!"
It's adorable.
