2 Stone Gods after the Professor

I seem to be missing some of the pieces of this puzzle that you fit together. The stone god on the right...his eyes are blinking blue and I can't move the pieces any more which indicates to me that it is correct......however....the one on the left seems to be missing pieces so I can't fill that space up. It looks sort of like a maze but it's not.
What am I doing wrong? I don't have any inventory and there doesn't seem to be another room to move onto yet. I have clicked on the "hints" but it doesn't show me any more pieces.
Thanks,
Jackie

Comicseller, look in the trees and the crotches of trees and between trees for the missing pieces. There are a couple that all you can see is a couple of squares. When the two tetris puzzles are correct the eyes of the statues stay solid blue. If one is blinking, it may mean you have all the correct pieces but not in correct position. Try picking up the plus sign and turning it. When both statues have solid blue eyes, click on the beetle and the spider at the top of the statues. That continues that puzzle to the next step. Good Luck.

Thank you for your help. I am going there now.
