Synopsis
Living together in harmony at Yoshi's Island, the Yoshis are able to maintain a perpetual state of joy through the fruit-bearing Super Happy Tree. However, Baby Bowser becomes envious of this happiness and casts a spell to transform the entire island into a pop-up storybook. In addition he also steals the Super Happy Tree, further weakening the Yoshis and making them fall to gloom.
While successful with his wicked deed, six eggs were yet able to survive the trial and hatch. Confused about the dismal state of their world, the baby Yoshis knew that something was amiss. And so, deciding to fight the gloom with cheer, they set out to retrieve the Super Happy Tree and restore happiness to the island.
On their way to Baby Bowser's castle, the Yoshis must progress through the six pages of the storybook, encountering six different areas of the island. While each page consists of four courses each, the path to Baby Bowser's castle will only consist of one course per page. After progressing to the castle and completing one of the final courses, the Yoshi in play will face Baby Bowser in a final showdown. Following his defeat, a final narration will convey the story from each of the six pages and courses the Yoshis went through, ending with the Yoshis standing together in joy, encircling the Super Happy Tree.
