Okay so I bet you've heard of "My Little Pony Friendship is Magic", right? Anyways, there is this game called Super Filly Adventure (I'll give you the link at the end), and it has 3 endings. Or 2? I forget. Maybe 3. Yeah it's 3: Muffin Ending, Warrior Ending, and Blank Flank Ending. Anyways, one of the endings is a scary one, and here are the rules to getting that scary one:
1) The Super Filly Adventure Blank Flank ending can only be activated from 11:00pm to 3:00am, so you gotta play the game between those times.
2) You must talk to EVERY PONY, and you must do it MULTIPLE TIMES. (Like talk to them until they keep saying the same thing over again)
3) When you talk to Applejack and make the muffins, choose only the items to the right to make the good muffin.
4) Give the muffin to Derpy (the gray pony with the derpy eyes) and talk to her until she says the same thing over again.
5) FINALLY go to the waaaaaaaaay end until you see a Zebra striped pony (it's passed Applejack) and from there, the background should be nighttime and the zebra pony should have red eyes, if it doesn't, you made a mistake and have to restart the game again :C
6) Go in the forest annnnd you'll have to find the rest out for yourself
