Gravity Falls

In a dimly lit cabin, Dipper Pines and Mabel Pines react with shock and fear to a small pink pig and then to a group of glowing-eyed zombies dancing in a room. The scene begins with Dipper and Mabel startled by the pig, then shows Mabel's angry expression as she confronts Dipper, before cutting to a view from behind Dipper looking at the zombies.
