As a fairy, you were gracefully soaring through the air when you suddenly encountered a massive, gray creature. It had strikingly vivid green eyes, a coat with a swirl pattern in shades of gray, and a notably long, rat-like tail. What caught your attention the most was the sight of this creature skillfully constructing what appeared to be a tower made of rocks. It gathered the stones and meticulously stacked them, ingeniously using its saliva and grass to bind them together.
