Rotating spiked platform

From Sonic Retro

Sonic 1

• Found in the Green Hill Zone, this obstacle comprises a horizontal, spiky pole stretching between riverbanks. Large thorns rotate around this pole in a spiral-like fashion, forcing the player to move and jump carefully.

Sonic 3

• Found in the Angel Island Zone, this spiked pole is very similar to the version found in Sonic 1 - however, it is much shorter, and rotates faster at a more infrequent rate.
• Can also be found in the Marble Garden Zone - This is a much thicker vertical platform, spiked on the sides. It moves both on all the axes - some move up and down, some move back and forth, and some do both.
