It is nearly ten times the size of a human, large enough to easily envelop a person in an instant. The fur is extremely soft, fluffy, and pleasant to the touch; even if it gets wet from rain or water, the fluffiness is never lost and it always maintains its texture. In winter, it evolves into an even fluffier state with winter fur. They also move in groups of hairballs made of many bundled strands. Its name is the Forest Carpet (commonly known as Fluffy Tentacles). It is an unclassified plant-animal hybrid that inhabits mossy areas of cool, damp primary forests. Its entire body is covered in fluffy, ultra-fine soft hair, and it wriggles smoothly using internal cartilaginous tissue and elastic muscles. While originally a pale color close to white, it blends into the surrounding landscape by mixing with the color of symbiotic moss. It feeds by entangling and absorbing microorganisms between its hairs, and even fragments of about 40-50cm that have been detached can move independently. Though they are tentacles, they do not prey on humans; they have a gentle personality and are accustomed to people.
