it took me awhile, but you have to keep going right. keep trying to go 3d, there are places where you can go slim to get through and places that paths appear. keep trying doors. once you get to a green one with an old guy inside (very right of a place.. you get big mario before you get to him) then once you talk to him turn down his offer of 1000 coins for a paper, then turn down 100, accept 10. (he might go to 1 coin but I did 10.) then go all the way back to the porta potty and click it, then give the guy the paper you got from the old guy. once you get this new pixl, go back to the ancient stone head with the lightning bolt above it and use the new pixl on itt.
