Ice Flower

Ice Flowers are the opposite of Fire Flowers. Ice Flowers first appeared in Mario & Luigi: Partners in Time. The effects of an Ice Flower are similar to a Bros. Flower, but they allow the Mario quartet to shoot ice balls instead of fireballs. Ice Flowers can randomly lower the enemies' Attack, Defense, or Speed.

Ice Flowers reappear in Super Mario Galaxy and Super Mario Galaxy 2. Ice Flowers turn Mario into Ice Mario, which lets him cross water and lava by turning it into ice as he steps on it. Additionally, instead of running, Mario will skate about the level, increasing his speed. The music for it will get faster and faster as it runs out, until it ends.

Ice Flowers reappear once more in New Super Mario Bros. Wii. In this game, they function as a combination of the Fire Flower from previous games and the new Penguin Suit from the same game. They allow Mario, Luigi, and the Toads to launch ice balls to freeze opponents without the other effects of the Penguin Suit, such as belly-sliding.

Trivia

 * A Fire Flower from Super Mario Bros. 3 in the roulette card game resembles an Ice Flower.
 * When Mario has an Ice Flower in New Super Mario Bros. Wii, his overalls turn red and his hat and shirt turn a light blue, resembling his original color scheme in which his colors were inverted from his current design.
 * In New Super Mario Bros. Wii, Yoshi can grab an ice ball thrown by another player and spit it out. This also works for fire balls from a Fire Flower.
