1. Go to the Lighthouse. Notice how the red arrows (below) are pointing at 3 suspicious-looking shapes: a diamond, a circle, and a star.
2. Now, notice the lamppost that is on the left of the lighthouse entrance, and how the top sign has the same 3 shapes. Click on the shapes in that EXACT order (*The order changes every time).
3. Once you’ve done that, the bush on the right should slide away, revealing the SECRET ENTRANCE!
4. Click on the elevator to see what Dr. Finkelstein has been hiding all these years!! O.O
