Shake King

The Shake King is a pirate first appearing in the game Wario Land: Shake It!. The Shake King and his pirate gang attempted to take over the Shake Dimension. In order to do so, they attacked the Shake Dimension and imprisoned its ruler, Queen Merelda, and also the Merfle on their ship. The greedy pirates stole the Shake Dimension's treasure as well, the Bottomless Coin Sack, which could spit out coins whenever they shook it, granting the Shake King and his minions infinite plenty. However, one Merfle managed to escape from the pirate ship and got into Wario's world, and asked Wario for help for the Shake Dimension. If Wario collect all of the Boss icons, Wario can locate the Shake King's ship, where the Shake King waits on Wario's arrive.

In normal levels, if the timer reached zero, the Shake King will grab Wario, shakes all of his collected stuf away and throw him back to the checkpoint or even worse.
