Dot Matrix

The Dot Matrix is a dot matrix printer with four hands coming out every side of it. It's the result of an incident on Floor 6, and now roams the halls of Floor 4, guarding the Witch's "Cauldron".

Boss Fight Strategy
With this boss, you have to avoid making sounds. This does not include flashlight clicking or checking drawers. If you run or walk too close to it, the Dot Matrix will charge at you and grab you, then stab you in the head and toss you away once you've been damaged. It can also spit acid on the ground to get you out from under a table when it knows you're there. If you get grabbed by the Dot Matrix, there is a short period of time where you can open your inventory and use an ink cartridge, which will cause it to drop you and leave you alone for a few moments. Doing this will give you the Ink Thirst achievement.

When you first enter the arena, Super Toad will come up and press the button that moves the cubicles, locking you in. The Dot Matrix will not be activated yet, so you can explore the arena freely. There are 8 tiles total on the ground and walls that you cannot interact with yet, but it's suggested that you place glowsticks at every tile you can see.

In the top right corner of the room, there's a cabinet that you must open in order to start the fight with the Dot Matrix. Inside will be Kate, who warns you not to run, basically telling you how to deal with the boss. The Dot Matrix will then activate, starting the fight. Head down to where the Dot Matrix had been resting, and grab the button that was resting underneath it on the floor.

Use the button from the inventory on the tiles on the floor/walls, and three of them will move the cubicles that allow you to escape the arena. Once you've done so, leave through where the cubicles had parted from at the top of the arena. Once you've walked closer to the cave ahead, Brian will turn around to head back, but the Dot Matrix will begin to crawl up from the arena. Run back towards the cave, and this will initiate a cutscene.
