Freezer Mobile is the tenth boss in Sonic the Hedgehog 3 and Sonic 3 & Knuckles when playing as Sonic and Tails, and is the ninth when playing as Knuckles. The boss is found at the end of Act 2 in the Ice Cap Zone.
The Freezer Mobile is a modified Egg Mobile with an extended platform attached on a pole to the base of the Freezer Mobile. Shooting out from both sides of the platform and also from the base of the Freezer Mobile is a freezing mist which can freeze the player into a block of ice. When playing as Knuckles the platform also draws itself up and down but remains stationary when playing as Sonic and Tails.
As Dr. Robotnik is too high to be attacked normally, the player must wait for a safe moment to jump on the platform under the Freezer Mobile, avoiding the freezing mist, and attack from there. After 6 hits the platform breaks off, causing Dr. Robotnik to come down lower to attack as the mist now appears out of the back of the Freezer Mobile as well as the base like before. At this stage he is in within reach to attack without aid.
