Quick answer

Bring the hammer and magnet, take the left cellar door, and finish the mouse-hole interaction. A community correction says the shovel may be needed before digging; keep the tool order flexible if the key does not appear.

What to do

  1. 01
    Bring the cellar tools.

    Collect the hammer, magnet, and any shovel or weight the cellar route exposes before choosing the door.

    Use the magnet at the mouse hole.

    Take the left door, apply the magnet to the mouse hole, and collect the key when the interaction opens.
