The Rat is even more withered than he was in the first game. His left ear is also broken and his hands and feet are exposed. He appears to have a torn cloth covering, and a seam can be seen running down the middle of the head.
The Rat is a withered, eyeless rat animatronic, with a faded brown color. He is replaced by Monster Rat and Shadow Rat during main gameplay. While The Rat doesn't appear in the main gameplay of Five Nights at Candy's 3, he is seen in the Night 1, Night 3, and Night 5 cutscenes. He also attacks Mary's brother in Night 8's minigame resulting in the closure of the Rat and Cat Theater. This is further proven by the fact that the Rat seems to have human remains inside him upon closer inspection of his jumpscares throughout the games. This may be because of the incident seen during FNaC 3's minigames when two actors died inside the suits, potentionally haunting them. The Rat and The Cat seem to be the only animatronics that will brutally murder a teenager, at least in broad daylight. He is possessed by an actor from Rat and Cat Theater. He appears to get up and do something in the cutscene after completing Night 6.
Not much is known about him as he only appears in Night 5. He is unique in that he only activates on the last few nights. He serves as the main antagonist of Five Nights at Candy's, Five Nights at Candy's 2 and Five Nights at Candy's Remastered, and the overarching antagonist of Five Nights at Candy's 3.
The Rat is the main antagonist of the Five Nights at Candy's series. CAM 13 (only seen in CAM 9 in the old FNaC 1)
