Queen Merelda

Queen Merelda is a supporting participant in the game Wario Land: Shake It! for the Wii. She is the queen of the Shake Dimension. Merelda and her loyal subjects, the Merfles, were imprisoned by the evil Shake King and his pirate gang (who attempted to take over the locale and also stole the Shake Dimension's treasure, the Bottomless Coin Sack). However, one of Merelda's Merfles managed to escape into Wario's world requesting help to rescue the Shake Dimension from the Shake King's evil grip, as well as rescue Merelda herself.

Once Wario defeats the Shake King, Queen Merelda tries to thank the "brave hero." But then Wario interuupts her by chucking her across the room, and then steals the Bottomless Coin Sack, proving that Wario wasn't interested in saving anyone and only wanted the tresure.

Trivia

 * Queen Merelda's name is a pun on the Spanish (or Portuguese) word esmeralda which means "emerald", a green colored gem. Her name is also an anagram of "emerald".
 * She has a great similarity with Saria from The Legend of Zelda: Ocarina of Time.
