The creepy background music was extracted from a mlp fan made horror game I decompiled a while ago. The file name is called 01_paper_self.mp3
The animation at the end is by Tweek Animation studios. https://www.youtube.com/watch?v=EN0hEeKLMdQ
The Song used in that Animation is Derp Astley- Derp Roll'd by BaldDumboRat

Originally I just used the Rick Astley Never gonna give you up video at the end but it got blocked worldwide for copyright so I used the derpy version.
