Off Limits was a room attached the Tunnel of Glove that only appeared in the episode, "Tunnel of Glove." It was off limits to non-employees. The room mostly contains Fuse Boxes, Water Pipes, and Water Valves.
The room is blue with a red door, and on top, there is a big sign, which reads, "Off Limits."
It was the room that controlled all of the functions of The Tunnel of Glove. In this room, Patrick searched for SpongeBob, who went with Pearl to the Tunnel of Glove. When Patrick looked for SpongeBob, he found a sort of "electricity supplier", which looked like SpongeBob, so he ripped it off the wall and took it with him. The electrician realized what Patrick had done. While he was repairing the "electricity supplier," Patrick sat on and broke the lever, causing the ride to get stuck in "dangerous super-fast mode," and then used the "facilities" (which was really one of the main water controllers).
