Okay...I've wandered through both linking books from the primary "blue book with leaves" at my Relto.
I managed to operate the "monorail train" and to swim out and take a look around the little island in the watery scenario, but I still haven't accomplished much, let alone figure out the rolling ball and clock routine. Light on, door shut. Light off, door open. Ball rolls, but I don't seem able to do anything with the clock mechanism or the markings along the ball's circular channel.
A small hint as to whether I shoud go on to other linking books or figure out something more here first, would be very helpful. I'm confoozled..big time.
