frisk woke up in a strange white room. she could not remember what had happened or how she got there. as she got up, she saw something in the distance. she walked closer until she saw her friends. but as she walked closer, she noticed something strange. she noticed that chara, monster kid and the snowdin canine unit were there. but she also noticed something creepy....they all had no faces! as she scanned, she saw something that also caught her off guard:herself! frisk was puzzled. what on earth was everyone doing here with no faces? as she looked at each and everyone of them, a strange though occurred in frisk's head: what if you moved them? she moved doggo to sans' spot. to her surprise, sans, or the thing that looked like sans, moved out the way. she placed doggo in the spot where sans once stood, and to her surprise, doggo regained colour, but still had no face. soonm she was swapping everyone.
frisk stood back and admired the newly completed puzzle. doggo was in sans's spot, lesser dog was in papyrus's spot, greater dog was still in his spot for some reason, dogamy was in undyne's spot while dogressa was in alphys's spot.
meanwhile, asgore was in toriel's spot, toriel in asgore's spot, frisk in chara, chara in frisk,asriel in monster kid, monster kid in asreil, sans in doggo, papyrus in lesser dog and undyne and alphys in dogamy and dogressa's spot. frisk decided to leave but as she turned she suddenly noticed the figures were starting to rumble and turn white. frisk noticed that the room was getting brighter and brighter. frisk shielded her eyes, but started to feel faint. as she collapsed she heard a robotic voice saying, "SWAP COMPLETE...MODIFYING STORY.... CREATING DOGSWAP.........DOGSWAP COMPLETE.'
