Donald is portrayed as just a disembodied head. Donald doesn't seem to have any body so far, most likely due to the story this game is based on. His head has eyes but they are black and shiny. Unlike the original Donald Duck and the Donald Duck head featured in the original teaser image, he is missing his hat.
He will, albeit rarely, teleport into the Office, making screaming, duck-like sounds. It is theorized that he does this to attract PN Mickey to the office. Although considering the rareness of him teleporting in, it is theorized that he might be there just for scaring. He is non-hostile, similar to Balloon Boy in Five Nights at Freddy's 2.
It has been proven that he will leave after several seconds. Another method to get rid of him is to disable [[Meat Freezer|CAM 2], but this is the only camera which will make him leave.
Since the other suits are attracted by noise, Donald Duck will attract them with his loud distorted quacking. The suits will start moving more spasmodically once Donald leaves the office desk.
Donald Duck starts in Character Prep 1, before suddenly teleporting in The Office randomly.
