Enjoy beautiful arctic landscapes while exploring the yeti caves. Those giant creatures have overrun your arctic home and there's only one way to defeat them. You have to cut their food supplies!
So look out for their frozen fish reserves. Other penguins tried this before, but unfortunately they failed. Now they are imprisoned, but you can free them by unlocking their cages. Zoltan, the vulture, guards the yeti's territory. You need to reach the end of each area, before Zoltan reaches the Dark Yeti.
