Go to the Mordred Museum and get the library slip. (You can use the gold coin in the fountain.) Click on the stack of books to get it. Go to the castle library and see the lower-aisle shelf marked McM. Press it and the secret passage to the dungeon opens.

After locating a library slip in Mordred's museum, you locate a shelf tag in the castle library. Pressing this opens a secret passage below the floor. There is a dungeon with a robot prisoner and some moldy cheese on the floor. Take the cheese to the Princess's room and feed the robot mouse. To re-enter the dungeon (it's guarded), you will have to get the key to Mordred's laboratory from the secret meeting place (under the fountain).

There is no way to open the cell from the castle entrance. You can get in the back way, though. The robot is powered by a green fuel cell (the same as the saucer crashed in the mud swamp). (see the related question)
