Icicle Caverns

Icicle Caverns, or , is the fifth level of Frosted Glacier in New Super Mario Bros. U. It is unlocked via completion of Prickly Goombas!. Its own completion opens the path to Swaying Ghost House. It is also the only level with Ice Bros.

Layout
Most of this level takes place in an underground cave that is made almost entirely out of ice. A common hazard in this level are the icicles covering the ceiling. As with Freezing-Rain Tower, the icicles vary in size and can fall onto the player. Once in a while, there are a few icicles that do not fall on the player when the player passes them.

Star Coins

 * Star Coin 1: Near the beginning of the level, the player must find a small hidden area containing the Star Coin. The player must be quick; a giant icicle will block the player from reaching it. (see picture)
 * Star Coin 2: Not too far after the Midway Point, the player must bounce off the first Ice Bro in order to reach the green Warp Pipe that leads to the second Star Coin.
 * Star Coin 3: Near the end of the level, the player must take the lower path before the giant icicles fall. The player can then use the Warp Pipe to take the player to the third Star Coin. If the giant icicle falls and not in time, the player could use a Super Acorn and reach up the top path.

Enemies

 * Buzzy Beetles
 * Ice Bros.
