The Shells resemble some kind of trundling, pincer-wielding clam.
The spikes on the Shells are purely cosmetic, meaning they will pose no hazard when Sonic attacks them with a Spin Dash or Spin Jump. Upon the Shells' 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.
