Go to the bottom of Ocean Star, which is the location of Kouga sharks. Click on the shell with the mouse and a note will come out. Then go to the top of the Xiao Yun Star, put the feather on the nest of Tias, and a note will appear; Then go to the volcano star, light four molten bubbles, and then come out; Then put on the anti-freezing suit and go to the Khehlka spacecraft in the ice cave of Cecilia. There is a big ice surface (that is, the one that just came in the opposite side) pointing to the ice protruding to the right (maybe to the left). There will be scratches on the ice after you order, and a note will appear on the ice you order. All right, that's all. Don't blame me if you don't understand!
