Great Heep

The Great Heep was a monterous droid employed by the Empire to mine fuel ore on Biitu.

It operated an enormous processing plant in the early days of the Galactic Empire. It's body was composed of assorted parts from other droids and tubing, one side filled with various bouncing pistons, beating in an appauling, terrible rhythm, and one arm chopped off at the elbow. Grinding blades filled it's mouth, with tiny mechanical robots living in it's hull like worms would live in a mammal's stomach. Two dilerious humans constantly fed the beast's massive boilers with fuel, while a droid harem kept smaller, unassuming droids in luxury, treating them to oil baths (much like the one Luke treated C-3PO to on the moisture farm) and other droid pleasantries before their eventual demise, where the Great Heep would consume them to add to it's own structure.
