The Sixers had erected a large armored bunker behind Castle Anorak, filled with pallets of weapons and battle gear that had been teleported in by the Sixers before they activated their shield. There was also a long rack of thirty Supply Droids, which had been installed along the bunker’s eastern wall. Due to a lack of imagination on the part of the Supply Droids’ original designer, they all looked exactly like the robot Johnny Five from the 1986 film Short Circuit . The Sixers used these droids primarily as gofers, to run errands and fill equipment and ammo requisitions for the troops stationed outside.
