Intro. The world is a magical elevator that moves between infinite floors, each with a different theme or environment. The train floor is one of the most common locations where Pest or Poob can be found. Poob's Party House is a noisy and colorful space, connected to the chaotic energy of Poob Pest always prefers dark, quiet, or lonely places, while Poob likes festive and chaotic walks. Despite their differences, they always end up meeting in the elevator or on the floors, such as the subway as well.
