Cold Course is a cave that commenced when Drawcia turned Dream Land into a world full of paint. As the name indicates, this place takes Kirby to a path of cold. His main threat would be from the ice boulders.
The first part of this stage is a slippery path while icy boulders are constantly raining down from above Kirby. Near the beginning, there's a wall that he can go through to a small gap where the player can see a big, green switch, although Kirby can't go there yet. The second part has Kirby breaking walls to get through the stage, and a hidden door that leads to the big, green switch can be found. The third introduces switches that makes ice fall from the ceiling to create a floor/stairs. After that puzzle, Kirby falls down a chasm, where he can free a giant black ball. If he presses the switch and detonates the bomb block in time, the ball will break open a door which will go to the same secret room Kirby was in before. This is where Kirby can find the third medal.
There is a switch in this level that makes all blocks of a certain color disappear.
