Hidden in the back of her room, there's a simple looking bookcase. Well, I lied- it's not a simple bookcase. By pulling out the right book, the bookcase will reveal a secret passageway which leads several floors down to one room; the dome. This room is beneath the Le Puddle and through its glass walls reveals the depths of the sea, the very creatures beneath it. Several other water tubes are connected to the pool side in the room, and the rumor is that this was built for Mr. Crane's sake.
