The protagonist, a yellow and orange capped anthropomorphic mushroom, resides on a planet not unlike Earth. The life on this earth is peaceful, and the four seasons keep the earth inhabitable with life. One day, the infamous villain known as the Balloon Bandit attacks the earth, sealing the seasons away in magical balloons. Time eventually stops and the earth had become a lifeless, deserted wasteland. The mushroom realizes that if enough balloons are popped throughout the months, the seasons will return and they will revive the earth. The mushroom cannot do this alone, however, and has the destiny of the earth in the player's hands.
(Note that the DS port has no story and is instead a standard puzzle game)
