Egg Hammertank II is a mech built by Dr. Eggman and is the boss of Leaf Forest from Sonic Advance 2. As shown when fighting it, the mech has an arm with Cream the Rabbit inside its grasp. The player has to attack the cockpit to deal damage. The mech attacks by slamming its hammer down but it takes a while to bring it back up. After a few hits, the mech blows up and Cream is saved. From that point onward, Cream would be playable.
