The audio track from the red lake Easter egg, named “i.mp4”, has a 1 in 10,000 chance to play on the customisation screen instead of the normal menu music. If you start a night after hearing it, the audio will leak into the night. The first time I ever encountered this, I thought it was a bug.

@saikenshin45 can never get this, while I get it all the time in comparison.
