Shell

The Shell is an enemy that appears in Sonic 3D Blast. It is a mass-produced, clam-based badnik created by Dr. Robotnik.

Appearance
The Shells resemble some kind of trundling, pincer-wielding clam.

Overview
Shells are encountered exclusively in Spring Stadium Zone. In gameplay, they will wheel round and pursue Sonic if he walks nearby.

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 Flicky, which can be picked up by Sonic.
