Mechanotesseractoid, part 1

Synopsis
Onions and Flame Kid, after hearing about the imminent demolition of the Berlin wall (and with it, the unification of east and west Prussia and the fall of the USSSR), decide to relocate the mystery shack to Prussia to make use of local tax regulations. However, this is cut short because they find that all of the bulldozers were destroyed by a mysterious robot. Called Mechanotesseractoid, this war machine was built around a mechanotesseractoid brain to manage the armies of the USSSR. They confront the robot, however he escapes onto the train and a sudden blizzard stops Onions and Flame Kid from following.
