Egg Cube is much like a Jack-in-the-box toy. Its box has Eggman's insignia on it and it is mostly red with gray stripes.
Gemerl's head is located on the "Jack's" nose. Egg Cube is mostly gray with a blue ball in his ear. It has a red and yellow party hat.
Dr. Eggman with this machine will be on the right side of the area attempting to move forward. The player must stay in front of him and wait for the cockpit to come out; after that happens Eggman is free to be attacked. The Egg Cube will constantly shoot three
Guards enemies out. Also, Gemerl is the "jack" of the machine and he will be launched at the character in either a rocket or ball form.
