Secret Room Outside the Lighthouse!

I was exploring the lighthouse and I noticed when I clicked on the shapes, they light up! I figured it was kinda like the Grotto. The blue sign (it's not in this picture very much) has the code on it!

 A door then popped up, near the bushes.

                                                                 Then, I clicked it.    

I clicked on the door again and went underground.

                                           

It was pretty cool, and you could click on some things, and it would move around.

It was Dr. Finkelsteins 'secret lab'. It's a neat place to meet with some friends when you don't want interruptions, or just to look around in.
