New host Alfonso Ribeiro kicks off a new season with a package of “Animal Encounters” complete with an affectionate seal who jumps into a man's kayak to snuggle, a dolphin who gives a woman climbing into a boat a playful nudge, a sneaky raccoon is caught on camera climbing into the house through a doggy door to steal the dog's food, a woman finds a possum underneath her bed, and a practical joke is played on a group of teens who bite into caramel onions rather than apples.
