Off Limits was a building that only appeared in the episode Tunnel of Glove.
The building is blue with a red door, and on top, there is a big sign, which reads, "Off Limits".
It was the building that controlled all of the functions of Glove World. In this building, 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).
