Penguin is back with a new friend and a new boat, this time in the jungles of the Amazon. Penguin, Rabbit, and Raccoon are exploring South America when their adventure takes an unexpected turn: a baby capybara washes up next to the Amazon River, all alone. To find his family, Penguin and friends must voyage through the croc-infested jungle—and little Cappy must find the courage to show them the way.
