These penguins are very particular about their ice. They can only touch ice that is the same color they are. So if they are a red penguin, they have to touch red ice. You can cut the string that a penguin is hanging from to get it to touch the ice. You can cut ice as well. A block can only satisfy one penguin so sometimes you may need to cut the ice in half. Once the penguin gets its proper ice you will complete the level and be able to move on to the next one.
