Idleverse

There's been countless other idle universes running alongside our own. You've finally found a way to hijack their production and convert whatever they've been making into cookies!
Overview
The Idleverse is a building with a randomized appearance in the building overview, sharing that feature only with Grandmas and Cortex Bakers. Unlike Grandmas, however, Idleverses do not need upgrades or Seasons to gain an altered appearance. Its icon can appear in several color variations, and its overview also uses a distinct alternate background.
Idleverses have the longest building description in the entire game. The building’s gallery includes several palette variants, and the same set of appearances is reflected in its overview presentation rather than being tied to progression unlocks.
