Level 108 is a school cafeteria. This level is popular among some people because there you can eat and rest with other people like You.
But You can still be killed by a math teacher that often comes here and You can choke to death while eating some very tasty "Hot-Dogs".
To get here You need to no-clip in Level 0. And to get back (to random level) You need to eat a thing called "BackToRoom".
