Dr. Eggman has Sonic trapped on his Egg Conveyer which leads to a pointy death, made worse by the projectiles. But Dr. Eggman's own control booth can't stand the conveyor belt's friction. Outlast the metal to give Dr. Eggman a hot foot.

— Description, Sonic the Hedgehog Encyclo-speed-ia

The Egg Conveyer[1] is an object that appears in the Sonic the Hedgehog series. It is a device created by Dr. Robotnik, who used it during the Little Planet incident.



The Egg Conveyer is a single person, large booth located in a room in Quartz Quadrant, which has a conveyor belt on the floor, a set of spikes in the left area of the room, and a bomb-thrower on the roof. The booth's color depends on the timeline; in the bad future, it is turquoise-colored, while it is purple in the good future.

Features and abilities

The Egg Conveyer's booth is very resistant against Sonic's attacks, as his Spin Attack and Spin Jump cannot damage it. The booth also has two levers, which can be used to move a bomb-thrower on the roof.


Sonic the Hedgehog CD

In Sonic the Hedgehog CD, Dr. Robotnik used the Egg Conveyer for an attempt to destroy Sonic the Hedgehog in Quartz Quadrant. However, the machine ended up destroying itself after going up against Sonic for too long.


The Egg Conveyer is the boss of Quartz Quadrant in Sonic the Hedgehog CD, and the fourth boss overall. While in the original version it is only faced by Sonic, the 2011 remaster makes it possible to face it with Tails.

Boss guide

The fight takes place in a closed-off arena. On the the right side is the Egg Conveyer's control cockpit, and on the left side is a wall with spikes. Initially, there will be a Conveyor Belt on the floor. The fight begins when the player hits the cockpit hanging above the Conveyor Belt with Dr. Robotnik in the middle. Robotnik will then descend with his cockpit and the Conveyor Belt will activate.

Contrary to other fights, the player's task is not to hit the Egg Conveyer, but avoid the boss's attacks for a certain period of time. The Egg Conveyer itself cannot be attacked, but it will damage itself over the course of the battle. The Egg Conveyer itself attacks the playable character by dropping bombs onto the Conveyor Belt. Notably, the player only has a moment to react before the bomb is dropped. When the Egg Conveyer drops a bomb from its cannon on the celling, it will explode upon contact with the ground and split into two smaller bombs on each side, all of which will explode on contact with the playable character. After dropping the bomb, its deployment device will hide. After a few seconds though, the attack repeats itself.

While the player cannot attack Robotnik in his cockpit as this boss will eventually defeat itself, the playable character cannot remain in an idle position. Standing still will cause the playable character to be dragged into into the spike wall on the left, and continuing to run to the right will eventually leave them open to a bomb being dropped on them and inflict damage. The player can avoid them in two ways. The first method involves continuing to run to the right until the bomb is dropped. The player should then stop and let themself get dragged closer to the spike wall while maintaining the speed necessary to avoid it. After the bomb and its fragments have dispersed, the player can resume running at full speed. The second method involves the opposite action: allow the deployment device for the bomb to get close to the spike wall and, after it has dropped its bomb, go as far as possible to the right in order to avoid the bomb. If the bomb does drop close to the playable character in both cases, it may be necessary to jump to avoid the smaller bomb fragments.

Regardless of the bombs dropped and how the player avoids them, the cockpit with Dr. Robotnik in it will slowly wears down as a result of the friction with the Conveyor Belt. Over the course of this battle, the cockpit of the Egg Conveyer will collapse onto the Conveyor Belt a total of four times, which causes Robotnik to panic more and more. After the fifth collapse, Eggman will make an escape from the Egg Conveyer and stop the Conveyor Belt as the Egg Conveyor is destroyed. After that, the path to the Capsule will be unlocked.
