(I DON'T OWN UNDERTALE. The only characters I own are Bailey and Creame.) All the monsters live happily in the underground: until one human ruins everything. Bailey Hill is a normal, 11 year old girl- until she trips, and falls into Mt.Ebott. Quick to befriend the monsters, Bailey is instantly loved by everyone. When monsters start mysteriously disappearing, Bailey is on the case. What she doesn't know, though, is that a small team, co-led by Undyne and Sans, are working as secret spies in the background. After hearing about the disappearances, Bailey thinks she can solve the mystery- but when Bailey has a shocking realization, she realizes that she might not be so innocent after all. ------------------------------------------- Changes: IMPORTANT: Frisk and Chara don't and never exist(ed) Monsters don't mind the underground, so Alphys never did the experiments. Still Relevant: Mettaton never left, and Napstablook is constantly being featured on his show The amalgamates don't exist since those monsters never fell down. Napstablook and Shyren are now younger than in-game, Napstablook - 12 and Shyren - 14. More on Napstablook- Since Mettaton never left, Napstablook is just shy. Everyone knows each other Alphys x Undyne- Already a couple Frisk and Chara don't and never exist(ed) ------------------------------------------- A note from Emma- Hi hoomans! I hope you enjoy this AU I came up with! Happy reading! 😊 10/4/2020: There IS a sequel coming soon! :D
