Traveling again, the four encounter the King of the Fairy Beavers. The King agrees to help them reach Oz, if they invite him for a visit — and Shaggy is happy to oblige. The protagonists and their beaver companions make their way under the Deadly Desert through the Nome King's tunnel (see "The Emerald City of Oz"). They pass the barrier of invisibility that shields Oz from the outside world, and arrive in Oz — only to stumble into a crisis. Conjo has used the magic compass to reach Oz, where he grabs the Wizard's black bag of magic and locks himself in the Wizard's laboratory. Conjo wants to supplant the Wizard and gain control of Oz for himself. The Fairy Beaver King defeats Conjo with his water magic, squirting a jet of water from the Forbidden Fountain into Conjo's mouth. The now amnesiac Conjo is easy to manage and reform; he is returned to his island in Twiffle's care, for re-education. Twink and Tom enjoy a pleasant stay in Oz before Ozma sends them home once again.
