It’s time for the annual Corn Maze Festival. The farm is bursting with activity. Cluck! Whack! The chickens build a fence around the cornfield. Moo! Thwack! The cows give the barn a fresh coat of paint. Thump. Quack! Duck builds the ticket booth for the hot-air balloon ride. Everyone is excited. Well, Duck is not excited exactly. But he has a plan. As Farmer Brown designs the corn maze for the festival, Duck does some designing of his own. Guess who’s in for a big surprise?
