I know this may be a stretch, but hear me out:

So... when Sideshow Bob put on the Burns Suit, he faked a springlock failure to trick Nedlyonette into thinking he's dead. But that got me questioning; did springlock suits exist in the FTAH universe?

Sideshow Bob must've known what a springlock failure looked like to fake one, which means he must have seen springlock technology in use at some point. But *where* that was is the question.

It can't be `The Diner`, because if memory serves correctly, Moe & Nigel found the endoskeletons for Abe & Burns in a junkyard. So my guess is that the Springlock Suits could be from some other establishment we don't know about yet (Possibly in a later installment like SL?).

But I'm just speculating here. Perhaps future installments would either confirm OR debunk this idea, knowing Nick has the whole series planned out.
