As seen through the eyes of two excited green youngsters, a steady parade of guests arrives for the annual Halloween party in the woods. Once the festivities are in full swing, and the various creatures are treating one another to some good scary moments, an alarm is called: "Here come the scariest creatures of all!" And in a clever wordless sequence, the monsters scatter to hide from . . . the approaching group of terrifying human children! In his charming debut as author and illustrator, David Costello captures all the fun of the holiday in his glowing watercolors.
