Egg Hammer Tank II

Egg Hammer Tank II (エッグハンマータンク2) is the first boss of Sonic Advance 2, appearing in Leaf Forest. It is a large buggy with a hammer that lashes out at the player. It has a large hand, and when you fight it the first time, it holds Cream and her Chao Cheese.

This boss is defeated with 8 hits. The first time you do that playing as Sonic, Cream and Cheese will be set free after the machine explodes, and they will fall on the hedgehog as he keeps running. The level then ends, and a cutscene plays featuring a surprised Cream thanking Sonic for saving her. Thus, Cream becomes a playable character.
