Forgotten Oswald is a demon in A:DI
Forgotten Oswald looks similar to Ink Bolt Oswald from Nightmare BEfore Disney, but he has Nightmare Suicide Mouse's right hand. He also has his ears broken and his eyes are hollow with a large grin on his face. That's about it.
Forgotten Oswald starts in the meat freezer. If you don't close a camera when he leaves, he will run to the office and kill you.
