Pengo

The Pengo is an enemy that appears in Sonic 3D Blast. It is a mass-produced, penguin-based Badnik created by Dr. Robotnik.

Appearance
The Pengos resemble short black and white penguins with yellow feet and beaks. They also have gray plating on their shoulders, chest and face, and possess pupil-less white eyes.

Overview
Pengos are encountered exclusively in Diamond Dust Zone. In gameplay, they simply waddle back and forth along a straight diagonal. They can only harm Sonic if the hedgehog walks straight into them.

These Badniks can easily be destroyed with a Spin Dash or Spin Jump. Upon their destruction, they release their respective power source, a Flicky, which can be picked up by Sonic.

Trivia

 * The Pengos share their name with the 1982 Sega arcade game of the same name.
