×All three skulls in the pressure plate area.

×Movement order matters. You want one eye behind the other, not under.

This can be done on either side, but the maneuvering is a little tricky. What I do is move to one of these spots with both eyes chasing me:



The slower eye ends up closer to the middle, whichever side you do it on. The process is a little different for each side, but the basic idea is the same.

I'd have to double-check my demos to see exactly what I did from there, so let me know if you need more help.

×-Get to one of the north exits of the Entrance. I got to the NE exit with skulls at (17,9), (18,4), and (19,4).
-Get to the south stairs in 1N. This is much easier with a skull at (17,9) because it's trapped in the walls.
-Complete 2N. The broken walls in the middle are good for manipulating skulls in preparation for several other floors on this level. It's not too hard to clear, either.
