Another idea (forget me not post) · 3:16pm Nov 22nd, 2012
Pinkie Pie helps game developers in making scary shooter game.
She is inside game that is being developed and nobody understands how she got in there (she is not in source code and there are no files with her). But she persists on helping and even gives a few good advices such as "make a hissing sound here" or "Paint a blood blotch here in this air duct" with occasional thoughts about balloons and streamers and everything Pinkish.
This continues on and on till some of developers decide to make a "Pink Room" as an easter egg for users to find.
With the release of game Pinkie Pie returns to Equestria and tells about her adventures, but everyone think that she just has a wild imagination. Till she describes all the bloody scenes that were made by developers. End is ponies in doubt about where Pinkie got this idea because it is out of character for her to think like this and... It is odd that they thought about her as being OOC.
P.S. I think it is somehow reference to Dead Space. Maybe I should re-play it soon.
Or should play less X-Com.
