The Egg Ball[1] (エッグ ボール[2] Eggu Bōru?) is a vehicle that appears in the Sonic the Hedgehog series. It is a modified Egg Mobile created by Dr. Eggman, who used it during an attempt to establish the Eggman Empire.

The Egg Ball consists of two parts: the first is basically the Egg Mobile inside a transparent, blue ball, with a gap that reveals the cockpit in which Dr. Eggman sits. It is also decorated with a white star inside of a reddish orange center. The second part is a mechanized, iron ball-like sphere decorated with the Eggman Empire's decal.

Features and abilities

While not having any remarkable features, the Egg Ball's user can control both the Egg Ball and accompanying iron ball. Both of them are also capable of flight.


Sonic Advance

In Sonic Advance, Dr. Eggman used the Egg Ball to try and destroy Sonic, Tails, Knuckles and Amy in Casino Paradise Zone. However, the Egg Ball was destroyed by the heroes, thus forcing Eggman to eject from the vehicle in his Egg Mobile and flee.


The Egg Ball is the boss of Casino Paradise Zone in Sonic Advance, and the third boss overall. It is battled with Sonic, Tails, Knuckles or Amy at the end of Casino Paradise Zone Act 2.

Boss guide

The boss fight simply consists of Dr. Eggman (in his mobile) and the mechanized iron ball will appear out of tubes randomly and travel in a horizontal or vertical direction towards another tube. The player's objective is to hit Eggman's Egg Ball to defeat this boss; hitting the mechanized iron ball instead will damage the player. The more hits Eggman sustains however, the faster he and the mechanized iron ball will move, increasing the difficulty. The player can also try pausing the game just when the Egg Ball appears on-screen to give themselves enough time to anticipate the movements of Eggman and the iron ball. To defeat the Egg Ball, a total of eight hits on Normal mode, or six on Easy mode, must be landed on it.
