I am stuck on the scene with the large dinosaur with the big nostrils. Got inside, raised some claws, pulled some rope and watched the ball in his airway float back and forth, pulled his tail up. But can't figure out how to get the next ball under his tail. Have no idea what to do with the large stone blocks that move up and down. Any ideas? Thank you

I'm stuck on the same puzzle. I think it is a snowflake, but it is not completely symmetrical and that makes me unsure. The hints haven't helped me enough to solve it. Good Luck!
