Screw Mobile is the fourth boss in Sonic the Hedgehog 3 and Sonic 3 & Knuckles and is found at the end of Act 2 in the Hydrocity Zone. The boss area is flooded with a small amount of water which Dr. Robotnik whirls up into a whirlpool with a fan attached to the bottom of the Egg Mobile.
At the start of the boss, Dr. Robotnik is too high to be reached from the floor so the only ways to reach him are via the bombs which he drops in the water, these shoot up jets of water into the air which, if the player jumps at the right time, will also propel them into the air as well. The other way is to jump on top of the whirlpools that Dr. Robotnik creates. Whilst he is creating his whirlpool, he pulls the water up into the air, which will also pull the player towards it and, if they get swept up into it, straight into the spinning fan on the bottom of the Egg Mobile. Once Dr. Robotnik has finished, the whirlpool slowly moves back into the water, the top of which can be used as a platform to reach him.
