When Harvey can't make the wrestling team, Sabrina uses Dragon Spray to help him. The stuff actually works, making Harvey a star wrestler who can even beat Slugloaf. But Harvey thinks the spray gives him luck and he takes more than he should. It causes him to grow to Dragon size proportions and he destroys the town in search for more spray. Sabrina must get Harvey to remember what it's like being his old self in order to get things back to normal.
