Casper is bored with his life and quickly finds himself transported to Changeland, where the people use their changing magic to make strange and useless alterations to the things around them. When Casper wants to leave, they change him too, making his head blow up like a balloon while his body remains the same size.
Casper convinces the people of Changeland to change him back to normal and send him home, but they follow him back to the Enchanted Forest and use their changing magic on the countryside and the animals that live there.
Casper asks the Changelanders if they have ever thought of making things better with their magic but they don't understand the concept. He almost has them persuaded to reverse their changes when The Ghostly Trio arrives and nearly ruins everything.
Spooky has a dream where he makes friends with all the animals in the Enchanted Forest and no longer wants to scare them. When he wakes up, he calls it a nightmare!
