Loneliness is something many humans hate. You especially dislike it and sometimes just wish that you had people over at your house. No one really talked to you anymore. Until you are looking through the attic and find a 'wishing stone'. Then your life changes forever. (ORIGINAL FROM WATTPAD)

You were woken up by an little puppet only 5 inches tall, Wally? You were interested in the Fandom where there were tons of universes of wallys... but... seems like your favorite has come to visit? To all who read there will be random pics I find online or that I ask to be made or that I made. I will say if I asked for them to be made or made them myself. Otherwise I found them from Google. Enjoy and just say if you want any wally's added otherwise imma make this a oneshot ordeal on top of an actual book so each tiny has their own storyline- feel free to ask for specific character ideas and i don't know much about all of them. I didn't make any of the Wallys in this book so please know I don't claim originality of these creations.

Nightmare found a young child a long time ago. When they fell into a coma it sent him over the edge. several hundred years later the child wakes up in a castle of darkness, surrounded by people, er... skeletons, that they don't know. Now they are being raised by murderers, cannibals, and world destroyers. Oh yeah! And their Uncle is the god of Death. Fun. WARNING (but not really): This story has been known to give people heart attacks and possible death from wholesome cuteness. I am not responsible for said medical emergencies or deaths. Read at your own risk. ~~~~~~ || Few things. 1) The first couple of chapters are going to basically just be Nightmare, but it's for plot reasons. 2) Dream is definitely going to be a little ooc. Don't like it, don't read. This is just for fun. 3) Like I said, this is just for fun. So, updates are when I feel like it. 4) I'mma try to keep the pronouns for (Y/N) gender neutral, but I may just drop that at some point. Depends mostly on what you guys prefer. 5) any art or videos added are not my own unless explicitly stated. Cool? Great. Let's get started.
