XB-135's Speed: Extremely Fast XB-135 will start at B-000, speeding towards the latest room. After it has reached the latest room, it will stay in the middle of the room checking a random type of hiding spot. After it's finished checking that type of hiding spot, it will speed towards B-000 and stay there, now being harmless. After a few seconds, it will spawn 5-7 random entities before B-135. After that, it will now be harmful and speed towards the latest room and check all lockers (blue lockers if it checked lockers), go back and rebound back to the latest room and check all tables (blue lockers if it checked tables), and then will rebound 2 more times. It despawns when it hits the unopened door on the last rebound. Strategy: Hide in the previous room since its first checking is RNG.
