Wario receives an antique globe and telescope that allow him to travel to the once-idyllic Shake Dimension, now conquered by the tyrannical pirate, the Shake King. With the assistance of his longtime rival, Captain Syrup, he must rescue the Merfles, denizens of the Shake Dimension imprisoned by the Shake King. Only by defeating the bosses of all five continents of this strange world can Wario find and confront the Shake King, rescue Queen Merelda, queen of the Merfles, and, most importantly, claim the Bottomless Coin Sack, a never-ending supply of gold.
