The Tin Woodman is reunited with his Munchkin sweetheart Nimmie Amee from the days when he was flesh and blood.

The Tin Woodman, the Scarecrow, and Woot journey into the Gillikin Country and encounter the inflatable Loons of Loonville, whom they escape by popping several of them.

After they oil his joints, he identifies himself as Captain Fyter, a soldier who courted Nimmie Amee after the Woodman had left her.

The five come to the dwelling of the tinsmith Ku-Klip where the Tin Woodman talks to himself—that is, to the head of the man (Nick Chopper) he once was.

Ku-Klip reveals that he used Fyter's head and many body parts from each of them (which never decayed) to create an assistant whom he named Chopfyt.

The companions leave Ku-Klip and continue east themselves to find Nimmie Amee at the foot of Mount Munch.

The Tin Woodman of Oz reversed this trend; its first-year sales of 18,600 were enough to make it a "bestselling success."

Even Baum's non-Oz-related early works were affected by the upsurge: John Dough and the Cherub (1906) sold 1,562 copies in 1918.

The psychological shock of the trench-warfare carnage of World War I[3] may have inspired a wave of nostalgia for a simpler time, with Baum's books representing a lost "age of innocence".
