NGC takes a fun-filled look at the stunning bonds animals form with other species, and even prey. A baby hippo is washed ashore after a devastating tsunami and latches onto a surrogate mother a 130-year-old giant tortoise. A lioness plays mom to a series of baby oryx calves, grooming and even fending off outside predators. These unexpected friends defy the laws of nature and demonstrate an evolution in the animal kingdom that would astound Darwin himself.
