What do you make of this big red lump on top of the under construction iterator can?
We've known since the beginning that iterators are (massive) purposed organisms, which are described to us as being more often than not "meat tubes in metal boxes"
Another good parallel to what iterators are would be cabinet beasts, brainmass in a box, which were said by the devs to be a good clue on how FP got the rot (and with watcher we finally get to see just how cerebral rot can get)
Downpour attempted to display this "guts in a metal box" aspect of iterators with The Rot in rivulet's campaign, although because of how development went, they had to reuse plant assets from farm arrays and sky islands instead of making custom meaty assets (they also used cabinet beasts for this)
Basically, that's their meat walls and gut corridors, don't mind it
