(Cover soon to come) In an AU where spirits frequently roam the world, spirit animals crossing a rift is a common occurrence. But when a rift opens in Gravity Falls, two children tumble out. Wendy, out on a bike ride, discovers them and takes them home. But will she know how to take care of them? (Note: This is an entirely original AU of my own creation, based on Monster Falls. If you want to develop it, write a story with this AU, please at least give me credit for the original idea.)
