Satellite

A satellite is a spinning spiked object that appears only in Super Mario Land 2: 6 Golden Coins. Satellites appear only in the final stage of the Mario Zone. Satellites are completely invincible obstacles that spin around spheres in a manner similar to a Roto-Disc or its Super Mario Land counterpart (with Perfect Ban Mario Character Daijiten even suggesting that the satellites might be a mechanical version of the former), though they are a bit slower.

 Satellite  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.''
