Plot:
The Scarecrow's falling to pieces... and it's up to Ozma and the Wizard to restore him to his former lively self... permanently. But the spell goes unknowingly awry, and the resulting adventure brings together Beenie Amerul from New Jersey, Mose--the boy from Australia, Captain Samuel Salt, Polychrome, and a host of other nutty characters!
Eleven-year-old Beenie puts on a Scarecrow costume that contains the Scarecrow's personality, meets a boy named Mose from Australia, and tells him the "Generic Story of Oz", in which Ozma always steps in at the end of the book to resolve the situation. When they find themseleves in an adventure and Ozma appears, Mose rudely tells her to butt out!
