The Tube Lobby is the room where the Tube Operators spend most of their working time. There is a computer, which they use to send agents all over the world. There are four tubes. (There is also a secret one in Ms. O 's office.) The tube operators say "Preparing to squishinate. Squishinating!" and "Incoming!".
- The tubes in the Tube Lobby also connect to the dinosaur room, the creature room and many other rooms within headquarters.
- In The Briefcase , Otto says that while riding in the tubes, "it feels like your insides get mixed up and turned around." Olive then confirms that your insides are literally "mixed up and turned around."
