At Ruby's house, a minor incident tied to the main plot of each episode takes place, before a red jewel on the chest of Choco, Ruby's teddy bear, flashes accompanied by a melody. Ruby then takes Choco to her room, and the two 'transport' themselves to Rainbow Village. There, Ruby receives an explanation from Ling Ling, the mayor of Rainbow Village, and transforms herself using her Rainbow Roller into suitable attire to resolve problems. Each episode concludes, back home, with another minor incident.
