Ice Piranha Plant

Ice Piranha Plants (also called Ice Piranhas) are a special variety of Piranha Plant first found in New Super Mario Bros. U. They are similar to Fire Piranha Plants, but spit Ice Balls instead of Fireballs. Unlike Frost Piranhas, another ice-based Piranha Plant sub-species, Ice Piranha Plants bear a red coloration.

New Super Mario Bros. U
Ice Piranha Plants make their first appearance in New Super Mario Bros. U. They look and act similar to Fire Piranha Plants, but shoot Ice Balls, which are capable of freezing playable characters as well as other enemies. They inhabit the world of Rock-Candy Mines, where three of them appear in the level Fuzzy Clifftop; two in a Warp Pipe and one on the ceiling. And just like Fire Piranha Plants, Yoshi can eat Ice Balls and spit them at other enemies.

New Super Luigi U
Ice Piranha Plants also appear in the DLC New Super Luigi U. In this game, they appear in Frosted Glacier with the same functions.
