Basically the joke was that this entry was meant to look like blueprints for a high-tech fluffy but turned out to be a fluffy tied to a big cage with a belt.
Their only attack is walking forward and pushing their cage into another fluffy. The cage is hollow so things can go through the gaps.
My advice for anyone trying to draw this is to only draw it from the side or just draw part of the cage. I included a perspective image (minus the backfaces) to show where the fluffy would be (the middle) and it was very difficult to figure it out.
