The Celebi Hall is a light green and somewhat "forested" hallway. The "forestry" comes from the several tree branches that extend from the walls and clime up to the ceiling, giving one the impression that they're in a forest. The floor is hard, but is painted so that it perfectly resembles grass. The doors look as if they were tree trunks. Statues of Celebi can be seen in the entrance and exit of this hall. Celebi Hall connects with Manaphy Hall. It is said that they change position each time a Celebi uses its ability to traverse time.
Note: Make sure to play close attention to the Physical Layout shown on the first post of the planning thread.
