"A Cunning Disguise" is a level in "Tide of Terror" in Sly Cooper and the Thievius Raccoonus. This mission is above the generator in "Prowling the Grounds". Sly enters an area which seems to be Raleigh's library. Sly needs to collect another one of Raleigh's Treasure Keys in order to proceed to the next area of Sir Raleigh's boat. Unfortunately, Sir Raleigh has booby-trapped the entire area, and dart-shooting machines will eliminate Sly if he walks on the rugs on the floor. Sly needs to use a barrel as a shield to avoid the darts. After obtaining the key, Sly can now take out the generator and access the other part of Raleigh's boat.
