Find the different one
You are standing in front of a wall
with a framed picture hanging on it.
Inside the frame is a drawing, and beneath the frame,
there is a button set into the wall.
It looks like a puzzle where you examine the picture
and press the correct button on the wall.
If you press the correct button, you should be able to
obtain a treasure hidden in a small gap beneath it.
