Upon entering the classroom/faculty room, Chalkles will appear on an empty chalkboard, slowly becoming solid as the player stays in the room. The player has 20 seconds to leave the room before Chalkles pops out. When Chalkles becomes completely solid, he will pop out of the chalkboard and then rotate around the room while making a creepy laugh-like sound, attracting Baldi and Dr. Reflex to Chalkles' location and preventing the player from escaping the room for 15 seconds.
