The Out with a Bang incident described on the film's main page. For detail...
Blue and eMMM in the Ice Cream Parlor by themselves. There's a decidedly creepy ambiance in there. Then, they here a scream, look out one of the windows and see the silhouette of someone as they are being impaled by a monster. All is silent, and they remain still, desperately hoping that they're not next.
The movie is twice as scary when you watch it with the DVD's Nighmare soundtrack.
