Earth World

Earth World (地上の国) is where the first half of the story of Rhythm Heaven Megamix takes place. It consists of various lands, inhabitated by various people.

Story
At the beginning of the game, Tibby accidentally falls off Heaven World. A mysterious individual (the player) finds him, and agrees to help him return to Heaven World. The two see a Green Tower in the distance, and decide to go to it. They pass through various lands, helping various people with their troubles by clearing Rhythm Games along the way in order to progress: After clearing all of the lands along the way, the duo finally reach Lush Woods, where the Green Tower, properly known as the Lush Tower, can be found. Here they meet Trey, who has been guarding the tower for a long time, and agrees to help Tibby reach Heaven World by having him and the player climb the tower, clearing Rhythm Games along the way to restore the flow to the tower, and thus activate it's power.
 * Honeybee Land, where Boondog is having an identity crisis after losing his flow.
 * Machine Land, where Dieter is unable to open his workshop.
 * The First Gate, where the Gatekeeper Trio challenge the player and Tibby in order to progress.
 * Citrus Land, where Shep cannot open his restaurant due to a lack of ingredients to cook with.
 * Donut Land, where Donna is feeling lonely due to there being no donuts around.
 * The Second Gate, where the Gatekeeper Trio challenge the player and Tibby again in order to progress.
 * Barbershop Land, where Hairold is unable to sustain his barbershop due to a lack of flow keeping customers away.
 * Songbird Land, where Eglantine is having trouble hatching an egg.
 * The Third Gate, where the Gatekeeper Trio challenge the player and Tibby once again before suppertime.

Using the power of the Lush Tower, Tibby rides a beam of green light up into the sky, but this is not enough to reach Heaven World. Trey informs him that they need a rainbow of power for that, after which others towers appear, each based on the theme of each land, guarded by the same people encountered in them.

After clearing them, Tibby has enough power to return to Heaven World. The story appears to be finished, however, Tibby sends a letter to the player saying there's trouble in Heaven World, asking for their help. Clearing Earth World is commemorated with a Badge.

Trivia

 * Not much is known about who lives in Earth World beyond the characters met in each land. Although none of the Characters present in the Rhythm Games are met during the story, several of them can be seen in various cutscenes, such as The Huebirds of Happiness flying out of the woods after Tibby falls down. It is also implied that the Café and Challenge Land, and by proxy every Rhythm Game that takes place on earth, are in Earth World.
