Koume and Kotake are twin witches that are recurring characters in the The Legend of Zelda series. They initially started off as antagonists, being surrogate parents to Ganondorf, but in the parallel world in The Legend of Zelda: Majora's Mask, they are friendly. Koume, the red, has power over fire, while Kotake, the blue, has power over ice.
Koume and Kotake appear as stage hazards on the Gerudo Valley stage in for Nintendo 3DS, and use their respective powers of fire and ice. Occasionally one of them will use their respective spell on one half of the stage. Koume sets the left half ablaze while Kotake freezes the right half.
