ice flower
A power up in the mario bros series that when collected, changes the palette of the player character and allows them to throw balls of ice that when it makes contact with an enemy, they get encased in an ice block which can be used as a platform or picked up and thrown, and the enemy will thaw out of the ice if left alone. If an enemy encased in ice is thrown and hits an object, the ice will break and the enemy will be defeated.
