He appears in One Night at Flumpty's. His method of intrusion is quite unique, not borrowed from any specific animatronic in the original series; he enters through a hole in the security office starting at 4 AM. While playing, you'll find the clown staring at you through the center hole in the office. Every time you raise and lower the monitor, he emerges bit by bit in the order of face-hands-feet-torso. If you open and close the monitor once he has fully emerged, he attacks. He essentially serves as a trigger to limit monitor usage. However, the number of uses allowed before he attacks is generous, so he isn't much of a concern unless you spam the monitor. He invades through holes that appear in the wall during the game. On Camera 2, there is a 'Patience Meter' in the top right; every time this hits 0, he enters the office. Unlike the previous game, he isn't that scary, but you must be careful as he has the second-highest exposure increase in the game. Appearing from 1:30 AM, he climbs the walls and approaches the front door. Cam 6, where he starts, looks like an art gallery full of clown paintings, and there is a 'No Photography' sign with his picture on it, which is a hint for how to deal with him. If you use the camera flash while he is right in front of the door, it triggers a jumpscare and game over; you must simply wait while checking the CCTV until he goes elsewhere. If Blam or the Eyesaur are at the same front door, you must wait for Grunkfuss to leave before driving the others away. As a side note, he is one of the least scary enemies regarding jumpscares. While others pop out without warning, he only attacks if you trigger him by flashing the light while he's at the door, meaning you're basically already dead the moment you see him there. Of course, it can be a bit startling when you accidentally trigger him, but the horror factor is low compared to others. By the way, he's handsome. He smokes often. He is a magical boy.
