To get the star you mean? Somewhere down the thread I posted a step-by-step walkthrough (and then a video🙄) for this star. But since I assume you want to try to solve it, here's a couple of hints:
- You can't get in to the star, so it has to come to you
- You will need to move two rocks and two medusas, and cross the ice patch three times. (not in that order obviously)
