Guruguri (グルグリ, from 「グルグル」 guruguru, onomatopoeia of spinning around) are spinning spiked enemies that appeared in Super Mario Land 2: 6 Golden Coins. Their behavior is extremely similar to that of a Roto-Disc, although they are quite a bit slower. They appear in the final level of the Mario Zone and are found spinning around spheres much like Roto-Discs. They cannot be defeated and will block Mario's path.
