This one is more easy than you though you just have to go in the king and queens castle and go to the right and enter the library. Go to the bottom shelf and click McM eventuly you are in another room go get the cheese on the ground. Click on the lever and go back up and feed the mouse the cheese.
it is McM
you give the owl the robotic mouse that was in the princesses room. And if you didn't get the mouse yet give the stinky cheese that was in the dungen. And if you didn't go to the dungen yet click on mcm in the library
The moldy cheese is in the castle library entrance to the castle dungeon. Get the gold coin from the fountain, pay your admission to the museum, and get the Library Slip. Now when you go to the castle library, you can click the shelf (McM) that opens the stairway to the dungeon.
Click the brick behind McM.
You click the McM place.
