    Random little oneshots and drabbles. Can be ships, can be x readers, can just be a story. I'll explain at the beginning of each chapter what it will be about. "Despite everything, it's still you."

    This is where we dump all of our story ideas that we are too lazy to turn into a real book. ~Alex Ya, pretty much. If we need to make room for more inspiration, this is where we shove the spare ideas. They should be well written, but without a major timeline.. ~KitKat

    Stories and headcannons I don't want to flesh out but I like. Anything from conflicts to love interests. If you ask nicely you can continue the story with proper credits.

    "Everything stays, right where you left it." OCTale's sequel Completed 10th November 2019. My interpretation of what happened after Tyler freed everyone. I recommend reading the first book, "OCTale: Pacifist", so you have a better understanding of what's going on, as well as "The Tale of the Two Siblings: An OCTale Story" to understand some of the later events of this book. Don't Forget and Uppertale are by RickyG. This story is based upon both. Credit goes to him for the ideas of the first 4 chapters. Credit to Camila Cuevas for inspiring me. Credit to Game Freak. I don't own Pokemon. Please don't give me a lawsuit. Trigger warnings for: Death Grief Depression Suicide PTSD
