His face also seems to have been cut vertically in the middle, making it resemble the cut Funtime Animatronics have to open their faces in Five Nights at Freddy's: Sister Location. He has brown hair accompanied with beige skin on his head. He has broken and shredded parts and holes all over his body, like the nightmare animatronics from Five Nights at Freddy's 4.
Nightmare Principal is a nightmarish animatronic version of the Principal of The Thing.
