It's time for the Wetmore Forest monsters to get ready for the big Harvest Festival! Creatures from near and far will celebrate with music, food, and games. But first, everyone must prepare for their guests: Picklez zips about picking up sticks, Butterhorn tries out the instruments, and Chester McFreckle even builds a machine to make pumpkin-pear cider. Children will love playing with the fun pop-up on every spread!
