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
- 01Bring the cellar tools.
Collect the hammer, magnet, and any shovel or weight the cellar route exposes before choosing the door.
- 02Use 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.
- 03Finish the mouse check.
Use the hammer on the mouse interaction. If the key is missing, re-check the shovel step rather than leaving the cellar.
