Nightmare The Rat is a fan made antonigist in Abandoned Discovery Island.
He appears like The Rat but he has a spike for his arm and for his left leg. His other leg is gone. His right eye has no pupils and is all black. His left eye has three human eyes.
He starts in the Janitor's Closet. Then he goes to the bathroom staring at you closely in the camera like a killscreen. Then he goes to the Meat Freezer. Then the office. You must shut off the power to survive. Shutting off a camera or hiding doesn't work.
- His behavior is the same as his normal self but he skips the lounge.
