Egg Saucers (エッグソーサー,Eggusōsā?)[note 1] are Badniks created by Doctor Robotnik and are only seen at Silver Castle Zone in Sonic Blast. There seem to exist three different variants of these Badniks with vary move and attack patterns. All three variants share basic round-shaped design with red, yellow, black and grey coloring. These Badniks have also seen to have small head with two antennas and tiny black eyes. Like many Badniks in Game Gear / Master System titles, these Badniks don't have Animals inside of them.
The first variant possess yellow rotating blades around their midsection. These Badniks float from side to side in a set area, and will move suddenly toward the player at high speed, when he/she's being spotted. These variants are seen blocking a particular routes and are rarely seen with couple of formations. This variant can be seen at moving spike wall sections, where the player has to move fast. The player is able to destroy this variant by jumping above to its head.
The second variant has small cannon on bottom of its facial section, which shoots multiple small projectiles to the player's neck. It moves up and down pattern with small yellow rotor in the top of its head. This variant is also seen at moving spike wall sections. Apparently these Badniks are always pointing and firing to the left and never turning its direction, which can make easy to attack behind of them.
The third variant has yellow, sharp-witted pogo which it uses to bouncing in one place, while at the same time being suddenly on the player's way, who would move too fast. These variants can oddly be bouncing at one place on small burrows and at the middle of spike floors. This variant is also seen at moving spike wall sections. It can be easily defeated by spin jumping to the without touching the sharp pogo on the bottom.
