There is no way to open it.You can open it if you go to the castle and go to the door in the right.That is the library.Press mcm in the non-fiction aisle.If it doesnt open,then go to the fountain and stand on the gleaming coin on the bottom platform.Go to the Mordred Museum,give the guy the coin,and press on the pile of books.remember this!!!!!YOU CAN NOT GO IN THE MCM ROOM 2 TIMES!!!!!!!!!!!!!!!!!!!Now go in the mcm room,and pick up the cheese.Flip the switch.There is your answer.If you like the way I write,look up my walkthroughs!!!
you can not
it is in the dungen cell.
The switch in the dungeon opens the back gate to the cell. Later, you can enter that way through Mordred's underground laboratory. (see related question)
give him the robot mouse from the cell
There is no way into the cell from the library. Throwing the switch opens the "back gate" to the cell, which you can access from Mordred's underground laboratory. (see related question)
The key in the dungeon doesn't work. You throw the switch and come into the cell from the back way. (see the related question)
The cell is only "blocked" by the bars on the dungeon side. When you throw the switch, it opens the back gate, which leads to Mordred's underground lab. (see related question)
Go back down and pull it. You need the gate open to reach the cell. (see the related question)
i do not know what you are talking about
The switch in the dungeon (the library entrance) opens the little gate in back of the cell. That's how you get into the cell. The tunnel leads to Mordred's secret underground laboratory, and you'll need a key to get in there.
You can't open the cell from the library side. Get the cheese and throw the switch that opens the back gate to the cell. You can enter the back way from Mordred's underground laboratory. (see related question)
You don't get in that way. The switch opens the "back gate" to the cell", so you can get in later. The librarian won't let you go in that way twice. (see the related question)
