Snowy

From the Super Mario Wiki

Snowy is an special attack acquired to Mallow in Super Mario RPG: Legend of the Seven Stars. Mallow attacks the whole pack of enemies summoning an huge snowman over them. The player must rotate the control pad to more effectiveness, dealing more amount of damage to the enemies. Mallow learns this attack at the level fourteen, and he must consume twelve Flower Points to use the attack. It is a very useful special attack since it's the only ice-based special attack the player can use, and then it's very effective against fire-based enemies.
