Frankenstein's Lab
S1: go to light house and then look at the post with the shapes on it
S2: Now look at the posts on the side with the shapes on them as well. Click the shapes in the same order as the ones on the post! e.g. 1st shape is diamond, circle and star (for me - don't know if it's different for anyone) then click the diamond first (on the post), then circle and then star. When you click on them they turn blue.
S3: Once all click and blue go over to the bushes and you'll see it has moved, you'll see this circle thing on the ground.
S4: click on the circle thing and it will pop up like an elevator.
S5: Click on the elevator and you'll be taken underground!
Ta da! There's really nothing do down in the lab
