You were a monster in the underground. Everything was going fine, till a human child fell underground. They had killed everyone in the ruins and Snowdin. You were the last stand against the human before Undyne. You were waiting for the human to arrive. You had to admit, you were pretty nervous l if a kid could kill all those monsters…imagine what they’ll do if they get past you.

You kept waiting for them to arrive, when you heard a splash behind you. This is waterfall after all, so it could just be the water. You still turned around nonetheless and saw…a human child. They were wearing a pair of ballet shoes, and a tutu. (Frisk can’t speak, so deal with it).
