It?s time for the annual Halloween picnic. But the kids are worried about the ghost of Titus Dinworthy. Except William, who?s pretty sure old Titus is just swamp gas; it?s Hester Bledden he?s worried about. Every time William is about to win a contest, Hester shows up, sticks out her tongue, and shouts, ?Peeee youuuuu!? But when something eerie rises out of the swamp, William gets a chance to show both Titus and Hester what a boy from Mudsock Meadow is made of.
