"Your Best Nightmare (Vocal Mix) - Undertale" is a high quality rip of "Your Best Nightmare" from the game Undertale.

Jokes Edit

This rip is a mashup of the advertised track and the song "Wriggle" by Clipping.

In the video description, the catchphrase is missing a period at the end of it. This is most likely a typo that went overlooked when uploading the rip.
