Game: Sonic the Hedgehog 3
Level: Hydrocity Zone
Hits to defeat: 8

Screw Mobile (スクリューモービル), the boss for Hydrocity Zone Act 2, is similar to the Big Shaker miniboss. As you enter the arena, the water level drops to the floor and Eggman flies in, his craft fitted with an impeller underneath and depth charges at the back. He flies from right to left above you, where you cannot reach him by jumping, but periodically lowers himself to the water (except for with Knuckles), revving up his impeller. During this time, it is possible to jump and hit the front of his machine, but when he hits the water you want to be as far away as possible.

Upon touching the water, he begins to draw it toward him, while slowly rising. This draws the water into a plume beneath him. If you do not move to the edge of the screen and hold this direction, you will be drawn into it. Being drawn into this plume will immobilize you and may cause damage, should you make contact with the impeller. When Eggman releases the water, he moves off and the plume begins to recede gradually. The top of the plume is solid and can be jumped upon to reach Eggman's machine, particularly as it drops to the water's surface. Be quick though, for the plume will settle and disappear about half a second after it stops on the water. As he flies across the top, he will drop some depth charges which, while damaging in the water, create a explosion that can launch Sonic high into the air, allowing an attack on Eggman. After eight hits his craft explodes.

Due to a bug it is very easy to avoid fighting this boss in Sonic the Hedgehog 3 alone. If you move too fast towards the right the screen will not lock and you will be able to destroy the capsule at the end of the level (though Eggman will continue to appear and attack off-screen). However, doing so can cause the transition between Hydrocity Zone and Marble Garden Zone to fail. This was fixed in Sonic 3 & Knuckles.

This boss also has a bug with Super Sonic in Sonic 3. When the boss is beaten, Sonic does not revert from Super. He can hit the capsule while Super, and stay Super till the Act ends. While Super, the 'Sonic' sign in the text will flash yellow like Super Sonic. This was also fixed in the lock-on title Sonic 3 & Knuckles.

If you dodge the bombs long enough in the beginning of the fight, the character starts drowning; strangely, jumping out of the water to stop drowning results in changing the boss music to the mini-boss music.
