How do I get the star element in the room with the eight closed eyes?

I'm stuck underground. I've collected all remaining elements (water, sun and forest), and now I'm trying to get that "star" element:

I guess I should find an eye or something to put on that blind tentacle, but I've looked throughout the level and found nothing. How I can solve this puzzle?


One eye awakes each time the mouth is fed a light-blue nut. You have to find the remaining blue nuts.

See how I am stuck with only one eye closed, yet I miss the sun too!
