Ep 4. Why?

Brothers Martin and Chris Kratt mix wildlife documentary, creative animation and humorous dialogue to present a program about all kinds of wild creatures. They are assisted at their research center by nature enthusiast Allison, and a wise-cracking, animated friend named Ttark. In this episode, the brothers attempt to answer puzzling questions about creatures, including "Why do animals play," "Why do animals live in groups" and "Why are there no bears in Africa?"
