The Legend of Zelda: Mystical Seed of Courage

The Mystical Seed of Courage was originally designed to be a sequel to both the The Legend of Zelda: Oracle of Seasons and The Legend of Zelda: Oracle of Ages. Mystical Seed of Courage was supposed to be released several months after the it's prequels arrived on the shelf. The project was soon scrapped after complications arose with linking the game to the other two.

Official Story
The official story follows as Nintendo described it.

''Princess Zelda, responsible for managing the four seasons of the Land of Hyrule, and the Triforce of Power have been kidnapped by Ganon. The brave hero Link learns of this and sets out to save the princess. However, Ganon learns of Link's quest and splits the Triforce into eight pieces, scattering them throughout the land. In addition, the Rod of the Four Seasons (a device that controls the seasons) along with its hiding place in Hyrule Castle, have flown off to another dimension. As a result of this calamity, Hyrule's four seasons are thrown into chaos and the order of the seasons becomes jumbled. In order to save Princess Zelda and find the "Rod of the Four Seasons," our hero Link must travel back and forth between Hyrule and this other dimension, while receiving help from the spirits residing in the "Tree of Mystery" and also the strange "Uura Tribe" found in this other dimension. Two characters that will help Link on his quest are introduced. The first is a kangaroo named Ricky. When Link climbs into Ricky's pouch, he will be able to jump and using a pair of boxing gloves, be able to punch out enemies. The other character is Maple. She suddenly appears flying on a broomstick and crashes into Link, bringing about various events in the storyline. The new item, the Rod of the Four Seasons will be required to solve certain riddles that appear in the game. Maybe the winter snow covers a secret entrance to a dungeon, and you'll need to change the seasons to uncover it.''
