A rare slime which is rarely seen. It has no official name, and is often called names such as "the weakest slime" or "crumbling slime." According to the catalogue of magical beings, "it is so weak that it may disappear if a strong wind blows or if it is poked." It becomes Ivy's friend, and they start their journey together. It eats a whole bottle of blue potion. (Source: Official site, translated)
