Baum's fifth Oz book is packed with more weird creatures and surreal adventures, but it is structurally weak and the characters are more or less non-entities. None of them have an arc (or even, in Button-Bright's case, a personality), and they just kind of wander from encounter to encounter, pulling deus ex machinae out of their pockets whenever they seem to be in trouble. It's wild and woolly but alsobland.
