Donkey Kong Country: Level 22: Ice Age Alley

Another round of Snow Barrel Blast. This level involves more ropes, though you won't be able to use them if you're riding on Expresso.

This level really does seem to follow up from Snow Barrel Blast, though. It continues the heavy snowstorm that level ended with, but then this level ends with clearing up from that same storm....
----------

There are only two Bonus Rooms in this level:

The first one is reached from a high platform where you have to bounce off from several Neckys. This is another room where you use Barrel Cannons to get some bananas, and then Expresso waits for you at the end.

The second room is reached by using Expresso for it. First, you must get far enough through the level to reach a Steel Keg, then leap off from there and flutter to the high platfom that leads to the Bonus Room. This room has you line up three balloons of the same color to get it. Either a red 1-UP Balloon, a green 2-UP Balloon, or a Blue 3-UP Balloon.
