Where?

Why aren't there bears in Africa? Why don't lions and elephants live in North America? Chris and Martin imagine a creature world gone crazy, where African and American animals live side by side with animals from Europe and Australia. With more competition for food, who will survive and who will become extinct? Allison and the guys examine why animals end up where they do, and how continents have drifted apart over millions of years. What will happen if the continents join up again? Allison and the guys imagine such a world, with strange results. Martin decides to plant new yard-trees for the elephants; Chris stops his car for lions on the prowl. It's a new sort of creature adventure, when the creature team changes all the rules.
