The Marvelous Land of OzL. Frank Baum
Set shortly after the events in the first book, the protagonist is a boy named Tip, who for as long as he can remember has been under the guardianship of a witch named Mombi (who is the main antagonist) in Gillikin Country. As Mombi is returning home, Tip plans to frighten her with a scarecrow he has made. Since he has no straw available, Tip instead makes a man out of wood and gives him a pumpkin for a head, naming him Jack Pumpkinhead. Mombi is not fooled, and she takes this opportunity to demonstrate the Powder of Life that she bought from another sorcerer. She sprinkles the powder on Jack, bringing him to life and startling Tip, whom Mombi catches and threatens to turn into a marble statue.
