Shaking "Shake King"

About

The Shake King is an evil pirate captain and the primary antagonist of Wario Land: Shake It! His design parallels that of Wario himself, with a similar rotund build, muscular arms, and stubby legs, along with a blue tint ringing his eyes. The Shake King has a distinctive spiky blonde beard, as well as hair on his arms; his eyes are black, with his pupils depicted as reddish-orange in official artwork and shown as yellow in game.

During the events of the game, the Shake King and his pirate gang, of many Bandineros, attempted to take over the Shake Dimension. In order to do so, they attacked the Shake Dimension, tied up its ruler, Queen Merelda, and imprisoned her loyal subjects (the Merfles), on their ship. The pirates stole the Shake Dimension's treasure, the Bottomless Coin Sack, as well, which has the ability to spit out an endless amount of coins every time it is shaken. However, one Merfle managed to escape from the pirate ship and get into Wario's world, to seek help in liberating the Shake Dimension from the Shake King's rule. If Wario collects all of the Boss Emblems, Wario can locate the Shake King in his ship to confront him.
