Control Room
From Inkipedia, the Splatoon wiki
The Control Room is the last floor within the Spire of Order that Agent 8 has to reach to clear the spire.
The Control Room first appears on Floor 10 during the first time Eight and Pearl go through the spire with Acht's helpin order to find and save Marina. In the center, Marina is being mind control to stop anybody who enters the spire as Marina Agitando.
After defeating and saving Marina, Order appears and throws the three of them out the spire. From then on, the Control Room moves to the 30th floor of the spire.
Reaching the Control Room is needed for Marina to reconfigure each Palette
