Satellite

A Guruguri (generically referred to by Nintendo Power as a satellite ) is a spinning spiked object that only appears in Super Mario Land 2: 6 Golden Coins. They only appear in the final level of the Mario Zone. Guruguri are completely invincible obstacles that spin around spheres in a manner similar to a Roto-disc or Kaitensuru Honō (with the Perfect Edition of the Great Mario Character Encyclopedia even suggesting the Guruguri being a mechanical version of the former), though they are a bit slower.
