About the AU

Project Undertale or "PUT" is a Switch Up AU. However, the switches make no sense whatsoever. My friend Middy now owns this AU.

Midnight, or as Trash calls her, 'Middy', is going to possibly make some fanart and sprites for this AU, along with an actual storyline and character development.

Character Swaps

  • Monster Kid switches with Frisk (and vice versa).
  • Flowey is the same, but is called "they" rather than "him".
  • Toriel is switched with Mettaton (and vice versa).
  • Napstablook is switched with Asgore (and vice versa).
  • Sans is switched with Alphys (and vice versa).
  • Papyrus is switched with Undyne (and vice versa).
  • Asriel is switched with Chara (and vice versa).

Character Changes

  • Sans still enjoys ketchup, but admits to Papyrus that he dislikes the use of it on Papyrus's spaghetti (don't even ask, let's just say that Papyrus puts ketchup on his spaghetti instead of tomato sauce.)
  • At the TRL Resort, MK can purchase TRL-Brand Pies for 50G.
  • Mettaton does not bake Monster Kid pie, instead he offers them 300G to stay with him. Regardless if they say yes or not, he will give it to you anyway.


  • Sans was originally Undyne and Papyrus was Alphys.
  • There were sprites for this AU, but they're gonna be remade.
  • This was originally going to be named, but the creator couldn't think of one.
  • This AU was adopted by Midnight from DITLOR.
