Sublevel 3

Description
Sublevel 3, or Unknown Residence, is the 3rd sublevels, and considered as the home and base of the smilers, according to ImCoolerThanAnyone12. This is why the sublevel is called "Unknown Residence". After you dodge every smiler, find the exit. There may be a button or a switcher door. Who knows. Anyways, you can go to Sublevel 4 when you find it.
