The Halloween special
N tries to find out what happened that caused the playground to be set on fire and if he had anything to do with it while a mysterious faceless figure known as the Slenderman haunts the group.
Twilight and Pinkie Pie are from My Little Pony Friendship Is Magic
Mabel and Dipper are from Gravity Falls
Mordecai, Rigby, and Thomas are from Regular Show
Slenderman is from Victor Surge
I only own N
I do not own any other character
