How to Solve Annoying Mouse Room Puzzles in Deltarune

Deltarune Chapter 2 introduces a series of quirky yet challenging puzzles involving mice and rotating panels. These puzzles, found in the Cyber World's Mansion, can be tricky if you don’t know the correct steps. Below, we break down each Annoying Mouse Room puzzle with clear solutions to help you advance without frustration.

Annoying Mouse Room Puzzle #1: The Basic Setup


The first puzzle is relatively simple but can still confuse players. Here’s how to solve it:
  • Locate the Green Panel – There’s a movable green panel in the center of the room.
  • Position the Panel Correctly –
    • Move to the left side of the panel.
    • Push it downward (toward the "Annoying Mouse Room" sign).
    • Then, push it right until it aligns with the wall.
  • Release the Mice – Press the button to let the mice out. They should now follow the path straight into the hole labeled "in."

    • Once all mice enter, the forcefield blocking your path will disappear, allowing you to proceed.

    Annoying Mouse Room Puzzle #2: Rotating Consoles



    The second puzzle is more complex, featuring three rotating consoles that alter the path of the mice. Follow these steps:


  • Left Console – Rotate it right eight times to position the red blocks correctly.
  • Middle Console – Rotate it right five times to adjust the green tile and red block placements.
  • Right Console – Rotate it left two times to finalize the path alignment.
  • Release the Mice – Press the button, and the mice should enter the hole.


    • However, the forcefield won’t disappear yet—you must release the mice a second time after Noelle inspects the control panel. This triggers a funny cutscene where Noelle gets launched over the panel, deactivating the barrier.

    Annoying Mouse Room Puzzle #3: The Hidden Phrase


    The third puzzle is less about logic and more about a humorous interaction with Noelle. Here’s what to do:


  • Release the Mice – Press the button to let them loose.
  • Rotate the Panels – Adjust the rotating platforms so the mice repeatedly hit Noelle.
  • Spell the Secret Phrase – As the mice bounce Noelle between platforms, letters will appear, eventually spelling "ILOVEMOUSE."
  • Complete the Puzzle – Once the full phrase is displayed, the puzzle ends.


    • Note: If Noelle falls, don’t worry—there’s no penalty. Just keep trying until the phrase is fully spelled out.

    Final Tips for Beating the Annoying Mouse Rooms


    • Experiment with Rotations – If a puzzle isn’t working, try rotating panels in different directions.
    • Watch Noelle’s Reactions – Some puzzles require her involvement to progress.
    • Enjoy the Humor – These puzzles are meant to be silly, so have fun with them!
