Old Chateau, Sinnoh Deepen in the forest, You found a...Mansion? You enter and explore this abandoned place for a while until You sense something is seeing You, hearing crumbles, cracks and some steps towards You from some direction, until You,frightened and shakened, turn back to the exit and see it, a Mimikyu —Peek-a-Boo! Chuckles —You should saw your face!
