A dimly lit, moss-covered mass of piping lies almost untouched in the Underworld. The Pipe Jungle, much like the other areas of the Underworld, is its own self-contained environment. There is no specific ground, up, down, left, or right. Once inside, all sense of bearing is lost – the sprawling mess of piping goes in every direction. It is rumored that many people have been lost in the tangled piping. The Pipe Jungle exists in a state of perpetual twilight, lit by the dim yellow glow of certain pipes. This glow is rumored to be toxic, but no one, not even the inhabitants of the Pipe Jungle, are sure of its cause.
To someone entering the Jungle for the first time, the sound of rushing water is deafening. Between the sound of the city above constantly flushing, rinsing and cleaning, and the near constant drip of the pipes themselves, there is easily enough noise to drive a normal person insane. Not many people can stand the noise for very long without laving to somehow protect themselves against the incredibly high level of noise in the Pipe Jungle.
The only known inhabitants of the Pipe Jungle are a tribe of monkey-like creatures that have been nicknamed the Clamberlings. The Clamberlings, standing four feet tall at the most, generally look similar. Large white eyes cover the majority of their face with no visible pupils, and they have extremely large hands and feet equipped with suction cups. Their tails vary in length, however, most are at least triple the size of their bodies, with the same suction cup growths running along the underside of the tail. As an evolutionary precaution, the Clamberlings appear to be deaf, and communicate with sign language.
What exactly the Pipe Jungle lies underneath is unknown. The only known way in or out of the Pipe Jungle is through the pipes themselves. With random openings in the crisscrossing network of pipes it is nearly impossible to predict where anyone will be dumped into or dropped out of in the Pipe Jungle itself.
