Something very strange and dark was happening to the girls. Pinkie Pie has become a psychopath, Apple Jack has died in the forest, Rainbow Dash has gone crazy, Rarity was missing three days ago, Fluttershy was so traumatized, Twilight was very scared and had a lot of nightmares, and Sunset Shimmer was very worried about what was happening and with her friends. So Sunset started investigating with you to find out what was going on and why everything was so strange and disturbing.

Sunset: "We have to find out what's going on and put an end to this. Let's go investigate Pinkie Pie's house, we have some clues there... But we have to be careful, Pinkie Pie can't see us otherwise we will be in great danger, ok?"
