You didn't have a bucket list or anything, but you wished you could've at least read a few more fanfics or done literally anything fun before dying. Oh well, at least you didn't have to socialize- Wait. Since when did dying mean becoming a doll in an Undertale multiverse? How did this happen?? This was inspired by a ton of reborn and reincarnated as Undertale characters fanfics and some other awesome stories! The main inspiration was 'Little Dream Doll' by KassyxTheDumbFox, and they got the idea from Firehedgehog's 'Idea Factory'. Beware, this story is fan fiction and is not canon, will include ooc characters, and I don't own Undertale or any of the characters, if you don't like that please read something else. This is my first story so there's no guarantee I will update regularly if at all, this is mostly self-indulgent. Btw, the cover's mine, please don't use it.

After Wish woke up from his 'interesting dream' he realized something was.... Off after a little bit, not only did he feel different but Ink and Blue looked at him as if they were waiting for him to explain something. This confused him to say the very least, Blue realized this and explained what they knew to him. His wish of him and his brother swapping places actually did happen, to a certain extent.... This outcome wasn't something he was expecting to happen, or thought could, he thought it was just a silly dream, turns out he really did rewrite the past.... Unbeknownst to him, he wasn't the only one who remembered this rewrite, and they were not pleased with his actions....

I have read many reincarnation stories in my life considering it was my favorite type of story to read but none were as cruel and sad as the one I lived. I had died a painful and agonizing death but when I awoke I was somewhere new. I didn't know where till I was told of my new name but this isn't about that or even about my time spent in this multiverse this is about the what is to come. or a story about someone reincarnating as nightmare sans but everything seems to go wrong for them ending in their multiverse eventual collapse. ink and dream were desperate in trying to find a solution to error and nightmares constant destruction and chaos ended up summoning someone from another multiverse in hopes they could help. they did not expect the person they summon to be a version of one of there greatest enemies.
