Felix appears to have his normal look, except his tail seems to have melted off, his eyes are closed, and his right ear is missing. He opens his eyes when in the office.
Felix starts on Night 4 (Unofficial). He starts off camera in the Broadcasting Room. He will then show himself and head through CAM X: Mickey's Clubhouse, Meat Freezer, Bathroom, Stairway, and Character Prep 1 then he gets to the office. Once in the office, the only way to get him out is to hide.
