Tibby's Mom

Tibby's Mom (テビリママ) is both Tibby's mother and his house, who appears in Rhythm Heaven Megamix. She is the queen of Heaven World and watches over her people.

Tibby's Mom is also part of the fifteenth stage in Rhythm Heaven Megamix, as part of Mamarin Palace in Heaven World.

Tibby's Mom is a large, golden castle with Left-Hand Tower and Right-Hand Tower beside her. While holding her breath, she has mainly a dark purple color scheme, with some pink, white, and blue. Her eyes are whited out, and the door below her is closed.

Story
In Rhythm Tengoku The Best Plus Comic 37テビリと天の国 (Tibby and Heaven World), Tibby is seen riding on a horse around Mamarin Palace. He loses his grip however, and falls down into Earth World.

At some point after this, his mom got the hiccups for the first time in her life, which the residents of Heaven World describe as a "spooky voice". She holds in her breath to cure her hiccups, which results in Heaven World being covered in gloomy clouds. This sets all of Heaven World into panic, and makes Tibby call the player into Heaven World to resolve the situation. They proceed to restore the flow along the way, removing all the gloomy clouds.

After Tibby and the player pass the Gatekeeper Trio's trials at The Fourth Gate, they finally reach Mamarin Palace. As Tibby explains that the guardians of Heaven World are destined to grow up into palaces like her, Colin interrupts to inform him of what has happened to his mom. He suggests the player and Tibby climb up to the top of the palace to ask her what happened face-to-face. In order to open the door however, they need to restore the flow to the two towers next to her.

After clearing them, Tibby and the player are able to enter the palace proper. They must clear five Rhythm Games within, namely Cosmic Dance, Cosmic Rhythm Rally, Working Dough 2, Karate Man Senior and Final Remix, and climb to the top. Upon doing so, Tibby tries talking to his mother. Although she doesn't respond, Tibby explains to her how much has happened along his way back, meeting a lot of people, and learning that everyone else has troubles like him. He says he has decided to live as one who helps others, but still gets no response from his mother. She then exhales, revealing she had been holding her breath to cure her hiccups the whole time, completely oblivious to everything that's happened. She notices Tibby brought along a new friend (the player), thanks them for helping her son and hopes they stay friends for a very long time. Clearing Tibby's Mom, and by extention Heaven World, is commemorated with a Badge.
