There are several rooms on both sides where the Cat appears and talks to the player. When going forward in the central room, the player enters a dark room, with the Cat standing in the middle of it, and an illuminated door, warning the player the danger that lays ahead. When entering through this last door, the layout of the rooms turn demonic, with a red tint covering the player's vision, and Specimen 7 now starts the chase.
After escaping Specimen 7, the layout of the rooms returns to normal.
- Before the 2.7 update, the rooms in which Specimen 7 chases the player did not count: the counter simply remained at Room 410.
