Bedroom

You're in a room with a bed in one corner and a tall cylindrical aquarium in another corner. There's an old rusty key for a padlock laying on the sand at the bottom of the aquarium. You can:

• go out onto the balcony
• go through a door to the right of the French window
• go through a door opposite to the French window
• fish up the key from the bottom of the aquarium, only if you have a string and a magnet
