| This article's name is conjectural.|
Although this article is based on official information, the actual name of the article's subject is pure conjecture.
The robot is not playable, and is instead used as an obstacle. E-10000Y is small, yellow, and floats just above the ground as it has no legs. Its main purpose appears to be capturing intruders in Eggman's base. When playing Egg Factory's frozen version, Ice Factory, the robots are instead spraying ice around the factory, and are still obstacles.
- They appear not to be able to tell the difference between intruders and Doctor Eggman, as they will attack even him when they see him.
