The Imp Stool is a small, organic mushroom with a distinctive, bulbous cap that features a smooth, slightly glossy surface. The cap is a vibrant purple hue with subtle gradient shading towards the edges, transitioning into a lighter, almost luminescent tone at the rim. The stem is thick and short, with a rough, fibrous texture, colored in a deep brown that contrasts with the cap. Tiny, glowing spores are occasionally visible floating around it, adding a magical, otherworldly effect. The overall shape is asymmetrical, with the cap slightly tilted to one side, giving it a whimsical, almost mischievous appearance.
