Kracko, but this one has more attacks and strengh. It is controlled by the squeak Doc. When you defeat Mecha Kracko, the cloud will disappear and you'll see Doc inside of this Kracko. You need to fight him again to get the Treasure Chest. Now, Mecha Kracko will destroy the clouds that make up the floor and will throw around enemies like Starman and Waddle Doo to attack you. When you defeat this boss, Doc will fall out and he will stay too dizzy and weak to move. Then, the treasure will fall out too. You fight this boss in Level 3 (Cushy Clouds).
