A looping animation features characters from the game Undertale, including a skeletal figure with a red cape, a pink character with a frown, a girl with a knife and glowing heart, and a skull-like character with a blue eye, all set against a black background with a horizontal line effect and the text "liam's galaxy" in the upper left corner. The sequence cycles through various character poses and expressions, including a character pointing, another falling, and a close-up of a character with a glowing blue eye.
