Chris and Martin think that cheetahs can travel faster than any other creature. Aviva and archenemy Zach Varmitech compete to build a ground racer that can run even faster than a cheetah.

It's Christmas time and the Wild Kratts are taking a break from creature adventuring to celebrate. They are beginning to open their presents when the Wild Kratts alarm sounds.
