"Hey," it said in a hushed, perverted, but perfectly executed Mickey Mouse voice, "Wanna see my head come off?"
It started to pull at its own head, working its clumsy, glove-clad fingers around its neck with clawing, impatient movements similar to a wounded man trying to pull himself free of a predator's jaws...
As it worked its digits into its neck... so much blood...
So much thick, chunky, yellow blood...
— Abandoned by Disney
Photo-Negative Mickey is the main antagonist of 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 Toon is actually a Mickey Mouse cartoon character 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 confirmed that this was the Ink-Blot version of Photo-Negative Mickey.
