Frozen Coins also appear in New Super Mario Bros. U in the level Piranha Plants on Ice, where they hold up giant Ice Blocks affected by gravity until melted by Fire Piranha Plants. They also appear in New Super Luigi U in the level Slippery Rope Ladders, where they function simply as obstructing platforms. Notably, both games have Frozen Coins appear slightly wider and with more ridges.
Frozen Coins reprise the aforementioned roles in New Super Mario Bros. U Deluxe.
Super Mario Maker 2
Frozen Coins were added in the version 2.0 update for Super Mario Maker 2, exhibiting the same behavior as in previous games. They can now be melted by any fire-based course element, except for lava, and the melting process is noticeably faster as well.
