Today's focus is on Roly, a baby black rhino at home on the African plains. The rhino is one of the largest animals on the surface of the earth but they all have to start somewhere. Roly may be small but he will grow up fast to become a herculean heavyweight. There is a lot to learn in his first year, from mud wallowing to browsing. This episode explores what frightens rhinos, why a certain little bird is a rhino's best friend and just how much Roly will have to eat each day to grow and become one and a half tons of hide, horn and hoof.
