Ice Flower

Ice Flowers are one of the many power-up items in the Mario series. This object can be found in a ? Block if Mario or Luigi is in his Super Mario or Super Luigi form. When obtained, the hero can hurl out magic Iceballs from their hands that can freeze many enemies during gameplay. This power-up appeared in New Super Mario Bros. Wii, and New Super Mario Bros. U among other appearances in other series, having the same function, except in Super Mario Galaxy, where Mario or Luigi gains a different ability. They are the frozen counterparts of Fire Flowers.

Mario Party 5
Ice Flowers appear in Mario Party 5 in the minigame Panic Pinball. If the player starts the roulette by hitting the Goomba, it is possible to get three Ice Flowers in a row, which gives the team 1,000 points.

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

Mario & Luigi: Partners in Time
Ice Flowers do not become an actual power-up until 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 Iceballs instead of Fireballs. Ice Flowers can randomly lower the enemies' Attack, Defense, and/or Speed.

Super Mario Galaxy
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 cold 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.

New Super Mario Bros. Wii
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 are often found in Towers and Castles. They allow Mario, Luigi, Blue Toad and Yellow Toad to launch Iceballs that can freeze opponents. Yoshi can grab an Ice Ball thrown by another player or an Ice Bro. and spit it out. This also works for Fireballs from a Fire Flower or a Venus Fire Trap.

New Super Mario Bros. U
Ice Flowers reappear in the game New Super Mario Bros. U for the Wii U. Their behavior is similar to that of their previous appearance.

Mario Tennis Open
In Mario Tennis Open, Ice Flowers appear as the Ice Flower Cup and its trophy, which has a different design.

Paper Mario: Sticker Star
Ice Flowers appear as stickers in Paper Mario: Sticker Star game for the Nintendo 3DS. When used, Mario is transformed into Ice Mario and hurtles an Ice Flower at any ground or low-altitude enemies, freezing them. If the attack depletes their HP, they shatter. This sticker also has two variants: the Shiny Ice Flower and the Flashy Ice Flower, which inflict more damage to enemies.

Mario Golf: World Tour
In Mario Golf: World Tour, Ice Flowers appear as an item shot. They let the ball freeze terrain wherever it bounces, letting players bypass water hazards.

Super Mario-Kun
The Ice Flower appears in volume 36 of the Super Mario-Kun, which is adapted from Mario & Luigi: Partners in Time. It becomes Baby Luigi's primary form of offense. After Commander Shroob destroys the snowman Baby Luigi had built, Baby Luigi pulls out an Ice Flower from the snowman's remains and defeats Commander Shroob and his Support Shroobs, while accidentally freezing his other three allies. He then uses a Fire Flower to melt them, scorching Mario in the process.

Baby Luigi then later uses the Ice Flower against Mario, after the four characters were provoked by a Tanoomba masquerading as them.

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.''

 * The Ice Flower is one of the two power-ups from Super Mario Galaxy that does not return in Super Mario Galaxy 2 through legitimate purposes, the other being the Red Star.
