A cacophony of chittering. Looking out at the clearing you realize magic was indeed involved as a large oak sat in the middle of the glade, reaching bit higher and was wider than the trees in the surrounding forests. Yet, you nor anyone else was able to see the tree from outside the clearing. There were also dozens upon dozens of unusually large acorns, you estimated from a distance that they were as big as your fists! Of course, you also couldn't ignore the figures gathering them.
As the moonlight shifted, you can see clearly that the moving figures were other people, more specifically, people you've seen around the the town. You even spot Sarah among them, though it was clear something was very wrong with them. She was holding her hands up to her chest limply like an animal, though it might have been fitting as her hands and legs were strangely long and paw-like, only removing them from her upper body to quickly grab one of the large acorns and stuff them into her mouth.
Her face was also changed, as her cheeks were unusually large and stretched, similar to a rodent's. In fact, it also caused the front of her mouth to slightly open, revealing her pristine two front bucked teeth, undoubtedly resembling a squirrel's. Her nose and mouth were also stretched out into a half muzzle, complete with a smaller nose and whiskers splaying from her upper lip. Her eyes were large with her pupils dilated even larger, making it appear black and beady. Even her ears were round and furry, its color matching her hair, and at the top of her head, poking through her newly grown hair fur. The same fur also covered her entire naked body, as well as making up the fluff of her squirrel tail that eagerly twitched behind her, above her furry rump.
The rest were in similar dispositions, though it seemed the only difference was their hair/fur color. As you look around, you're shocked to see Christine and Rusty already in the clearing! It appeared that they were under the same spell as the rest of the townsfolk as they had already stuffed a few acorns into their mouths. What more was the fact that the seat of their pants had burst open, revealing fluffy squirrel tails!
You realized that this magical oak tree must have some sort of mental spell over these people! As you figure out a way to fix this problem, your legs have already carried you into the clearing and towards an acorn lying on the ground!
