In the central western part of the Gillikin Country is a great tangle of trees called Gugu Forest. It is the biggest forest in all Oz and stretches miles and miles in every direction—north, south, east and west. Adjoining it on the east side is a range of rugged mountains covered with underbrush and small twisted trees. You can find this place by looking at the Map of the Land of Oz.  
Gugu Forest is the home of most of the wild beasts that inhabit Oz. These are seldom disturbed in their leafy haunts because there is no reason why Oz people should go there, except on rare occasions, and most parts of the forest have never been seen by any eyes but the eyes of the beasts who make their home there. The biggest beasts inhabit the great forest, while the smaller ones live mostly in the mountain underbrush at the east.
 
Now, you must know that there are laws in the forests, as well as in every other place, and these laws are made by the beasts themselves, and are necessary to keep them from fighting and tearing one another to pieces. In Gugu Forest there is a King—an enormous yellow leopard called "Gugu"—after whom the forest is named. And this King has three other beasts to advise him in keeping the laws and maintaining order—Bru the Bear, Loo the Unicorn and Rango the Gray Ape—who are known as the King's Counselors. All these are fierce and ferocious beasts, and hold their high offices because they are more intelligent and more feared then their fellows.
 
Since Oz became a fairyland, no man, woman or child ever dies in that land nor is anyone ever sick. Likewise the beasts of the forests never die, so that long years add to their cunning and wisdom, as well as to their size and strength. It is possible for beasts—or even people—to be destroyed, but the task is so difficult that it is seldom attempted. Because it is free from sickness and death is one reason why Oz is a fairyland, but it is doubtful whether those who come to Oz from the outside world, as Dorothy and Button-Bright and Trot and Cap'n Bill and the Wizard did, will live forever or cannot be injured. Even Ozma is not sure about this, and so the guests of Ozma from other lands are always carefully protected from any danger, so as to be on the safe side.
 
In spite of the laws of the forests there are often fights among the beasts; some of them have lost an eye or an ear or even had a leg torn off. The King and the King's Counselors always punish those who start a fight, but so fierce is the nature of some beasts that they will at times fight in spite of laws and punishment.
 
Over this vast, wild Forest of Gugu flew two eagles, one morning, and near the center of the jungle the eagles alighted on a branch of a tall tree.
 
"Here is the place for us to begin our work," said one, who was Ruggedo, the Nome.
 
"Do many beasts live here?" asked Kiki Aru, the other eagle.
 
"The forest is full of them," said the Nome. "There are enough beasts right here to enable us to conquer the people of Oz, if we can get them t............
