The rain of Mo is made of lemonade, candy grows on trees (which is where Santa Claus gets his supply), and lakes are made of milk. Everyone in Mo is immortal and the King and Queen have many, many children.
Milk River - A river that is made of milk. The islands in the Milk River are made of cheese, creams gather in small pools near the river bank, and great strawberries grow from water lilies. The sand on the river banks of the Milk River is pure white sugar and is excellent for growing candy and bonbon bushes.
River of Needles - A river that is a perfect stream of sharp glittering needles and blocks the path to the castle of Maetta.
Root Beer River - A river where peanut trees go near it. The Root Beer River flows down a great hole that leads to Turvyland. It is forbidden to swim in the Root Beer River for many people drink from it.

Bredenbutta – The forty-seventh cousin of the King of Mo, the great-grandniece of the Queen of Mo, and a noblewoman who lives in the Land of Mo.
Bumpy Man - Introduced in The Scarecrow of Oz, the Bumpy Man is a rugged-looking man with bumps all over him. He is also called the Mountain Ear because it is his duty to listen to the world around him and tell the mountain on which he lives about what is going on. Thus, it keeps the mountain from shaking, rumbling, and spouting. He sleeps little since he stays alert at night listening for the slightest sound.
Cast-Iron Man – A mechanical giant that was created by King Scowleyow to destroy the Land of Mo.
Gigaboos – A race of fearsome creatures that live in the Land of Mo. Its body was round with a thick shell (like a turtle's shell), its head was supported by a long goose-like neck, it had four mouths, seven bright and glittering eyes (each colored red, green, yellow, blue, black, purple, and crimson), ten short thick legs, and two arms with claws like a lobster that were strong enough to pinch a tree in two.
Hartilaf – A giant who lives with his wife in a valley that is next to the Land of Mo. Hartilaf is so big that he can make a journey to Alaska and South America and be back by sundown.
