Poptank  ( is an enemy that appears in ニシータ  Nishita ) ? . It is a mass-produced, hermit crab-based Knuckles' Chaotix Badnik model created by Dr. Robotnik.
The Poptanks slightly resemble hermit crabs.
The Poptanks only appear in
Marina Madness. In gameplay, they lack any kind of offensive capability, and simply trundle back and forth on the ground, or sometimes upside-down on the ceiling. As such, any attack available to the player will be enough to destroy them. Like many of the Badniks in the game, Poptanks are powered by synthesized Rings which they drop upon defeat.
