Level Fun appears to be a party room with cakes, hats, and partygoers, Level Fun is a very dangerous level that you need to get out of there if you are in it. There are many partygoers that are planning to end you, but whatever you do don't eat any cakes or try leaving through doors. You must noclip to leave. And note, the food is good here, but be warned its made out of HUMAN FLESH. Partygoers hate Partypoopers.
