chunk: The remainder of this book is Ojo's quest through Oz to collect the five components of an antidote to the Liquid: a six-leaved clover found only in the Emerald City, three hairs from the tip of a Woozy's tail, a gill (a quarter of a pint) of water from a dark well (one that remains untouched by natural light), a drop of oil from a live man's body, and the left wing of a yellow butterfly. With the help of the life-size patchwork doll named Scraps, Bungle the snobbish Glass Cat (another of Dr. Pipt's creations), the Woozy, Dorothy, the Shaggy Man, and the Scarecrow, Ojo gathers all of these supplies but the left wing â the Tin Woodman, who rules the yellow Winkie Country, which is the only place where yellow butterflies grow, will not allow any living thing to be killed, even to save another's life.
