Two brave individuals volunteer to experience life as an animal for four days. Farmer's daughter Char Counsell becomes a Harbour seal, while extreme sportsman Johno Verity becomes a Humboldt penguin. For the first time in the series, they won't be living in the wild or on a farm, but experience their animal lives in captivity, in a sealife sanctuary. Johno and Char learn to live, eat and swim like their animals, and even gain an insight into their sex lives.
