Photo-Negative Mickey Mouse is the main antagonist in the game Five Nights at Treasure Island. He is based on a creepypasta titled Abandoned by Disney, written by Christopher Howard Wolf. In the story, a man searches an abandoned Disney attraction called Mowgli's Palace, only to find a Photo-Negative Mickey costume, and a Donald Duck head with a skull in it. When he turns to leave, he turns back around and sees the Mickey standing behind him. It asks: "Hey... wanna see my head come off?" The Photo-Negative Mickey costume then proceeds to pull its head off, causing thick, chunky yellow blood to spray everywhere. The man, however, escapes from the suit and leaves.
As its name implies, the costume is actually a Mickey Mouse character costume with photo negative coloring. It is unknown why it was colored as such. It contains all of the classic Mickey Mouse features, such as circular ears, a small pointed tail, a pointed nose, a large grin, buttoned pants, shoes, and gloves. If reversed, it shows Mickey Mouse's original colors.
It has been shown to leak a thick, chunky, yellow fluid. The Face has also been shown to leak this fluid in one of the teasers.
In the first trailer, while jumpscaring the viewer, Photo-Negative Mickey's face changed into a very unnerving look with large, empty eye-sockets (much like The Face's) and a ghastly wide smile. It was Template:Confirmed that this was the Shade version of Photo-Negative Mickey.
PN Mickey starts at Character Prep 1 along with Disembodied. He is initially seen lying down. However, when he is about to start moving, he will stand up. This can help the player prepare for him. He appears in all but two cameras (CAM 4 and CAM 7) when active.
Advice from Greg explains that Photo-Negative Mickey is blind, but has a heightened sense of hearing.
However, Lisa explains that the suit can see, albeit poorly.
If PN Mickey appears in The Office, the player needs to pull up the Monitor and shut down a camera, the loud noise luring PN Mickey into another room. Delaying or neglecting to do so will cause him to kill the player. The player also has the option to hide under the desk, giving the player a 50/50 chance of surviving. PN Mickey will always reappear in Character Prep 1 regardless of which camera is turned off, and restart the cycle. On the 2nd night, the PN Mickey suit can sometimes reappear already standing, rather than lying down.
PN Mickey can also enter the Office from the left and right side of the Office once he has entered, which he appears from the left if he enters from the Lounge and appears at the right if he came from the Meat Freezer
