Classic Crazy

Crazy the Mouse, also known as Classic Crazy, is an animatronic mouse who hosts the Play Area. At nightfall, he becomes homicidal and will attempt to kill anyone in the restaurant.

Appearance
Crazy is a sea-green animatronic mouse who is constantly hunched over, almost like a hunchback. He has long arms in proportion to his body, similar to an ape. His mouth always gapes open, as if he was surprised, and his eyes are very wide with tiny pupils, further giving the impression of surprise or shock. Crazy wears a yellow hard-hat with a light. Crazy also wears a fluorescent yellow safety vest over a red-and-black plaid lumberjack sweater, with torn blue jeans and heavy work books, evoking the appearance of a construction worker.

Behavior
Crazy starts out in the Play Area. On Night 1, he will activate around 2:00 AM, and on later nights, he will activate soon after 12:00 AM. Crazy moves at a moderate speed and will take seemingly-random paths throughout the restaurant, lingering a while on each room, but nevertheless making his way towards the Office. He will attempt to enter the Office through the left door or the right door. He is easy to hide from and he will not usually stay at an entrance for long, but he is slightly aggressive and will likely approach the Office several times throughout the night, increasing in frequency on later nights.

Crazy will occasionally turn the light on his hard-hat on, illuminating part of the room he is in and making him easier to see. However, he may flicker the light on and off, disorienting the player and making it hard to see through the camera. Also, if he flashes the light while standing in a doorway, the player will be temporarily blinded for a couple of seconds. The light flashing becomes more common on later nights.

Trivia

 * In an Easter egg, Crazy may sometimes approach one of the Office doors with his hands covering his eyes, then throwing them out and saying "Boo!"
 * Another Easter egg involves Crazy flashing his light in Morse code, which translates to "THEY MADE ME DO IT", and "THEY'RE UNDERGROUND".
 * Crazy is Classic Silly and Classic Sneaky's younger brother. It is also possible he is related to Erased.
