Fall Mouse bears a strong resemblance to the original Mickey Mouse, but he has red eyes, he is gray and his features match the original cartoon Mickey Mouse. He is seen standing with his arms crossed behind, with the exception of the Meat Freezer.
When Fall Mouse becomes active, the TV in the Broadcasting Room will turn on and Suicide Mouse's song will occasionally play. For now, a death animation hasn't previously existed for Fall Mouse, but he had abilty to crash the player's game and will jumpscare you if he catches the player on the cameras. He also seems to block view of the rooms he enters, with the exception of Broadcasting Room. He also is seen standing at normal when in the Meat Freezer and The Office. When Fal Mouse enters Character Prep 1, the camera will be very darkened, but Fall Mouse will stay bright.=== Locations ===
Suicide Mouse starts in the Broadcasting Room, and will eventually enter Character Prep 1, the Staff Area, the Meat Freezer, and The Office.
The only time Fall Mouse will stand straight is when he enters the Meat Freezer.
The pose he uses when he enters the Meat Freezer is a normal standing one.
If the player manages to survive the Infinite Night for a long amount of time, he will block the player's point of view in the office revealing that it will play the same ambience from Five Nights At Candy's 2.
It is possible for Fall Mouse to blink up to 5 times as seen in his development idea.
