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 continue their examination of the "Arribada" ("The Arrival"), where sea turtles from all over the world have come to one island to lay their eggs. After the eggs are laid, numerous predators abound.
