When you get to level 7, go up a bit.Keep on breaking ice .Eventually you will break an ice which gives you the coin. You should get the stamp.Level 8- go up and you will see a yellow balloon holding a key. Carefully keep on pushing it upwards. Dodge the sharks and push it up and it will go through a lock. This will open and reveal a coin. You should get the stamp. Level 9- Act as its a normal level and rescue the puffles. But on your way back be sure to use the shortcut. When you are in line with the break in the red balls on the right, knock the balloon and don't move. You will pass through. Then repeat by knocking the the balloon and using the shortcut.Do it again.
