There is only one house here. You will find two penguins standing on each side. Now go to the shore west to the Great Healer. Jump across all the icebergs. Climb up the ladder and push the log into the water. Go back to the other side and walk across the log. Now (oh my god) PUSH the penguin across to meet her lover (doesn't she know how to walk?! ... ). The male will give you a color stone in return.

Nothing else to do. Leave.
