Ice Flower

Ice Flowers are the frozen counterparts of Fire Flowers and first appear in Mario & Luigi: Partners in Time. The effects of an Ice Flower are similar to a Bros. Flower, but they allow Mario, Luigi, Baby Mario and Baby Luigi to shoot snowballs instead of fireballs. Ice Flowers can randomly lower the enemies' Attack, Defense, and/or Speed.

Ice Flowers reappear in Super Mario Galaxy, specifically in the Beach Bowl Galaxy, the Freezeflame Galaxy, and the Deep Dark Galaxy. Ice Flowers turn Mario into Ice Mario, which lets him cross water and lava by creating hexagonal platforms of ice wherever he steps on either surface. Additionally, instead of running, Mario can skate about the level, increasing his speed. The music accompanying the ability increases in speed until the effect of the Ice Flower ends, in effect serving as a timer.

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 snowballs to freeze opponents. Yoshi can grab an ice ball thrown by another player and spit it out. This also works for fire balls from a Fire Flower.

Ice Flowers make a small appearance in Mario Party 9. In King Boo's Puzzle Attack, they're in the puzzle table among other items.

Ice Flowers are set to appear as stickers in the upcoming Paper Mario: Sticker Star game for the Nintendo 3DS.

Ice Flowers are set to reappear in the upcoming New Super Mario Bros. U game for the Wii U. They will behave like it's preqeal

Super Mario Galaxy Trading Card Description
''The Ice Flowers turn Mario into his Ice Mario form, which allows him to cross bodies of water and lava! Any liquid that Mario touches while in this form turns into hexagonal platforms that he can walk on and cross great distances. Ice Mario can also freeze waterspouts and waterfalls, which allows him passage to higher elevations.''

Trivia
