Grumble is one of the bosses you’ll meet after the Doors Floor 2 update, and solving the puzzle before you actually face it can be challenging. You can get lost searching for terminals or get killed before you reach them, and you’ll have to memorize the sticky notes along the way.

You’ll meet Grumble in Room 150 of the Mines in Doors, where you’ll be thrown from the minecart and have to run until you get to the safe room before the blast door closes. To move on to Room 151 and escape Grumble, you’ll have to activate the terminal and insert the code in several Anchors. The number of Anchors will depend on the number of players.

The antenna on the terminal will point to the direction of the Anchor where you need to insert the code it’s showing. The first one is in the safe room. As you leave to look for the next Anchor, be careful not to encounter Grumble in the mines, as it walks around and will chase you if it sees you. Avoid it by listening to its laughs, hiding in lockers, entering small passages, or returning to the safe room.

When you encounter the next Anchor, check to see if there’s a sticky note with a number on the screen. You’ll have to either take or add the number from the sticky note to every digit of the code you got from the terminal. So if you got code 154 and there’s a +2 sticky note in the Anchor, the code you need to insert is 376, or if the code is 738 and there’s a -1 sticky note, the new code is 627.

After you’ve activated all Anchors, go back to the safe room and click on the button on the terminal a final time to drop off the bridge. Grumble will start banging on the blast door, and you’ll have to run to cross the bridge, enter Room 151, and go down the ladder to escape.
