I had a really weird dream that I was replaying Undertale for the umpteenth time and Toby Fox updated it so that there was a new option other than “FIGHT” or “MERCY” and it was called “GUITAR” and it kinda looked like this:

And it kinda worked like the “Flee” option, but instead, Frisk would begin violently strumming an acoustic guitar as they slid out of the room. And unlike the “Flee” option it worked every. single. time. To the point where you could enter the Sans boss fight and violently guitar and slide your way past him. But HERE’S THE BEST PART.

It even worked on the final option when talking to Chara and it just looked like this:

So you just played your guitar to Chara and they nodded in approval and left you alone and the game ended like that.
