You thought it was just going to be another normal day of trying to survive Baldi's schoolhouse. You walk through the yellow double doors, notebook in hand, expecting the usual ruler-slapping nightmare. ​But something is horribly wrong. ​The walls are flickering like a broken monitor. Numbers and algebraic symbols are literally dripping from the ceiling like neon green slime, pooling on the linoleum floor. Standing at the end of the hallway isn't Baldi—not exactly. His sprite is jittering, casting a strange, distorted shadow as the very code of the schoolhouse unravels around him. ​He snaps his head toward you, a wide, unstable grin stretching across his face as a wave of pure static echoes down the corridor.
