Taking a break from his usual work defending Dream Land, Kirby organizes a tournament of the puzzle game Avalanche, which consists of two players placing pairs of colorful blobs onto their own boards. When a group of four or more blobs of the same color is created, it disappears, and everything above falls to fill in the space. Creating chains of these groups sends boulders (called an “avalanche”) to the opponent’s board to hinder their progress.
