Sans blue

A skeletal character in a blue jacket stands with a telescope against a starry night sky, while a larger skeletal figure behind him laughs maniacally; the scene transitions through a series of distorted, glitching images of the characters in various poses and settings, including one where the smaller character lies on the ground with a speech bubble saying "You're gonna have a bad time, kid," and another showing a close-up of a character with a cracked face and the text "Papyrus?".
