Can you hear the growling stomachs of the two Stone Age hunters Bone Breaker and Mammoth Masher? They're off to roam the wilderness in search of food. They split up so that they can maximize their efforts. On their way they find all kinds of nutritious things to eat: juicy mammoths and dangerous dinosaurs, thick lizards, but also useless bones.

In Ugah Ugah!, players help the two Stone Age hunters to earn the spoils. Whoever has the most munch points when Bone Breaker and Mammoth Masher meet up again has won the hunt.
