The Octopuses resemble a yellow and purple variant of their real-life counterparts. They also each have a trompet-like mouth with orange lips and cartoonish eyes.
Octopuses are encountered exclusively in Gene Gadget Zone. In gameplay, they each occupy a fixed position on the floor in their Zone. They function essentially as rotating gun turrets, shuffling themselves around to follow Sonic's movement and bombard him with blue projectiles.
These Badniks can easily be destroyed with a well-aimed Spin Attack, Spin Dash or Spin Jump. Upon their destruction, they release their respective power source, a red Flicky, which can be picked up by Sonic.
- This Badnik was given no official name upon or after the release of Sonic 3D Blast. However, its name was revealed in the Debug Mode for the unofficial Sonic 3D Blast: Director's Cut video game developed by Jon Burton, the lead programmer of the Genesis version of Sonic 3D Blast. When asked about its validity, Burton that this Badnik's name was used in the original game.
