He asked the whale to join them, so the penguins could jump, and with the help of the whale, they would be catapulted into a wall of ice and snow. Once in the air, the Yeti must throw snowballs and aim at the penguins. If it hits them, the penguins will end up on a wall of ice and snow, earning you points. You have to point the mouse pointer in the direction you want to throw and click anywhere on the screen right after the penguin jumps.
