Satellite

A Guruguri, also referred to 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 stage 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 that the Guruguri might be a mechanical version of the former), though they are a bit slower.

 Guruguri  Tribe: Mecha clan Disposition: Serious Game appearances: Land 2 ' Is it a mechanical version of Roto-Disc? ''This is a character that just goes around and around the balls in a circle. They are similar to Roto-Discs (p. 67) in both movement and personality. It is also difficult to avoid them when they appear in large numbers.''
