In Nancy Drew: Sea of Darkness, Nancy locates and collects Magnus’s sketches for his footlocker (trunk). The sketches are hidden in several places:
1. On the mast at the top of the crow’s nest on the ship
2. In Dagny’s suitcase
3. Gunnar gives you some after you help him fetch his box
4. In the captain’s bed in the quarters
5. In the ice caves
(To find them in the ice caves, follow these steps:
1. After breaking the wall, go forward 5 times. There is split on the path.
2. Go forward 6 times. See a ladder going up and one going down.
3. Climb the ladder going up.
4. There is a split to left and right. Take the right path. Go forward twice.
5. There is another split path. Take the left path. Go forward and then down into a large hole.
6. Take the sketch pieces in a plastic bag. Go back up twice.
7. Go right. Go forward 3 times until a split.
8. Take the left path. Go down the first ladder.
9. Turn around. Continue onward towards the exit.)
Click and drag each piece onto the trunk so that all the pieces make up a full drawing, and each piece stays in place. If you only have a few pieces of the drawing, you can still place the ones and they will stay until you come back with the rest.
Refer to the solution in the video for exact placement.
You know the puzzle is solved when Nancy comments on the illustration.
