Dismember Mouse is a fan-made antagonist in Five Nights at Treasure Island, alongside Photo-Negative Mickey and Photo-Negative Suicide Mouse. He can be a distraction by covering up camera within himself blocking it, obstructing the player's view to cameras.
Dismember Mouse is supposed to be a hallucination of what Jake saw in his life. He's controlling Jake's mind. Simply, he's almost a hallucination. Dismember Mouse can appear on some rooms at random, but you better not hide under the desk if he's in The Office.
He appears to be resembling as a Photo-Negative Mickey costume, but eyeless and his mouth remains shut, but almost open wide, He also seems to lack legs and arms. Disturbingly, fluently without any problems. He seems to be floating around when he's moving around in-gameplay, especially when he's blocking any cameras, obnoxiously obstructing the player's camera view. This event mechanic can speed up the suits.
Either way, he seems to have white buckles on his pants, unlike PN Mickey's black ones, and can float any of his body parts. Curiously, he has white oozes inside his eye-holes. Even though, he can still move without problems with an eyeless look.
He currently activates on Night 5 and on, He starts in The Roof remaining off-Camera, which when he comes our, he's floating on the chimney, Then goes to Character Prep 1, floating in front of the camera, He then goes to the Meat Freezer floating again. Then heads to the Lounge before entering the Office. Which takes 2 path from CAM 2 or CAM 6.
Either way, when he enters the Office, being directly floating in front of the player. The player must shut off a camera in order to get rid of him, Otherwise, he will attack the player. The player must not hide under the desk, because he will also attack the player by that.
While remaining active or moving around the building, he can occasionally speak one of these quotes, his voice is currently unknown :
Dismember Mouse starts on CAM 10, then takes his obstructing pattern to CAM 3, CAM 1, CAM 2, CAM 6 and gets into The Office as soon as possible. Disturbingly, he distracts/obstructs/blocks CAM 3 and CAM 2. Also when he enters The Office, he covers the player's view to The Office, especially like CAM 3 and CAM 2.
