Prickly Goombas!, or Frosted Glacier-3, is the third level of Frosted Glacier in New Super Mario Bros. U. It is unlocked via completion of Freezing-Rain Tower, and its own completion opens the path to Scaling the Mountainside and Icicle Caverns, both of which are sometimes blocked by a Cooligan enemy course. This level is where Nabbit appears again.
The player begins the level on a ground entirely out of ice, nearby two Fire Piranha Plants in Warp Pipes. A ? Block is found above a regular Piranha Plant, containing a Super Mushroom or a Fire Flower, depending on the player's form. Another Piranha Plant is found, along with a Prickly Goomba found next to a Fire Piranha Plant. Some rolling hills, Prickly Goombas, and Fire Piranha Plants are found. A Fire Piranha Plant is found in a Warp Pipe, followed by a ledge with a Prickly Goomba and three regular Goombas on it. The Checkpoint Flag is found, along with another ? Block. A rolling hill with a Goomba on is found, and a ? Block containing a Yoshi Egg is hidden behind a wall at the end of the hill. A Fire Bro is found, followed by a rolling hill with Prickly Goombas on it. Mario then arrives at a ? Block and a Fire Piranha Plant. A group of Prickly Goombas is found below a platform, with a Fire Bro burning their shells open. Another Prickly Goomba is found with a Fire Bro, followed by a rolling hill and a row of Piranha Plants in Warp Pipes. A group of rolling hills, Fire Piranha Plants, and regular Piranha Plants are found, with the Goal Pole at the end of the area.
