Classic Sneaky

Sneaky the Mouse, also known as Classic Sneaky, is an animatronic mouse who works at Silly's Taco World, managing the Arcade and dispensing tokens. At night, she becomes murderous and will try to kill anyone in the restaurant.

Appearance
Sneaky is a very tall bright green mouse animatronic. She has long, shaggy brown hair. Her eyes are dark green. Unlike her siblings, she has prominent incisors that are visible when her mouth is closed. She wears a stereotypical rapper outfit, with large hoop earrings, a lavender top that bares her belly, and lavender pants. She wears bright purple shoes.

Behavior
Sneaky will activate on Night 3, on rare occasions earlier, and starts out in the Arcade. She moves at a slow pace towards the Office, and will attack through the left door or the right door. Whenever she appears, she will cause the radio to experience heavy interference for a little while, making it harder to listen for animatronics upstairs. She will go away fairly quickly after the player hides.

In Extreme Mode, Sneaky is much more difficult to deal with. If she appears in a doorway, she will permanently disable the radio, making it impossible to tell if animatronics are upstairs. She will have to be lured away from the entrances by audio cues before she can enter.

Trivia

 * Sneaky is Silly and Crazy's older sister.
