Kruggy

Kruggy is an antagonist in the game, Nightmare in the Sewer. He is a rat housed under a sewer facility. After midnight, he is left to roam in the facility until 6 AM, looking for something to feed on. He starts from the Power Generator room, and approaches the Office from the right hallway to kill The Player. To prevent this, the Player must shut the door on Kruggy when he gets too close.

Appearance
Kruggy is a dark brown rat. He has amber eyes similar to "Minecraft" style eyes, and a white long tail.

Behavior
Kruggy behaves similarly to Gordon Ratsey. He starts to move on Night 1. Kruggy's starting location is on CAM 14, where he will make his way towards the right hallway to enter the Player's office. He will approach CAM 26 in two phases: entering and leaving. Then, he will make his way past CAM 13 and CAM 22 before slowly approaching the right hallway. He will have 3 notable phases en route. Kruggy can be viewed from CAM 1 on his first two phases. If the player does not shut the door in time while Kruggy is in his 3rd phase, he will attack the player, resulting in the game ending. If the player successfully stops him from entering the office, he will return to the beginning of CAM 26, instead of CAM 14 and restart his cycle.

Kruggy usually enters the right hallway at around the same time Gordon Ratsey enters the left. Usually, music plays whenever one of them if close indicating they are nearby. Once the music ends, it (usually) indicates one of them is gone.
