The Urinating Jiralhanae is an Easter egg found on the level the Ark.
When you reach the room with sleeping Unggoy, continue further towards the back of the room and there is a Jiralhanae urinating in a corner. Originally, he has his hands in front of him, but after a short time he will move his hands behind his head and then shake the excess urine off himself. After a while he will move into the main hallway and get into position waiting for intruders. The Easter egg can also be seen later in the level during the series of rooms directly before reaching the Cartographer. Strangely, if you look closely at where the Jiralhanae has urinated in, there are white spots or patches, rather than the normal human urine color of yellowish greenish. It is not known whether or not Jiralhanae have white colored urine or the same color of urine as humans.
- The Brute is not always the same rank. However, he is usually a Captain. Usually, if the Brute is a higher rank, he will notice you a lot faster.
- If you watch the Brute on Theater mode, he seems to be "zipping" or "pulling" up his pants before turning around.
- Due to the fact that there is no urine animation, and there are white drippings on the ground, some speculate that the Brute is actually masturbating.
