||Desert of Doom|
|“That's the Serpentine Valley, Wu. We're not allowed there. Father promised King Mambo, remember?”|
The Serpentine Valley was once a glorious, lush valley ruled by King Mambo, the leader of the Blue Vipers, in the time of the First Spinjitzu Master. Later in time, sandstorms covered the area except for the pyramids, making the valley the Desert of Doom.
