Night 1 is the first playable night of Five Nights at Mascot Island. Compared to the other nights, This night is easy since The FNAF Characters is the only active mascots in this night.
The Five Nights At Tubbyland and The Night Shift:Iggys Funhouse characters are the only the only costumes the player should worry about for Night 1. When a Suit enters the Office, the player needs to pull up the monitor and shut off a camera. Doing such will draw the Suit out of your Office and back to their starting location.
However, the player also has the option of Hiding, where Jeremy hides under the desk to avoid being seen by the Suit in the Office.
