Wanda

Wanda is a fairy who first appeared in the Japanese-only Super Famicom release, Mario & Wario. In this game, the player controlled Wanda using the Super Famicom Mouse, providing a safe pathway for the aimlessly-wandering Mario, Princess Peach, and Yoshi, who have had buckets dropped on their heads by Wario.

Although Wanda's first appearance did not come to the United States, she reappeared in another SNES puzzle game, Wario's Woods, which was also the last (licensed) game released for the NES. There, she helped Toad clear out monsters by providing him with bombs.

After only appearing in two games with Wario's name in the title, Wanda has yet to make a returning appearance.

Trivia
She has the same name as one of the fairies from the program Fairly Odd Parents.
