Investigative guides which reveal amazing facts about members of the animal kingdom. This episode features Wally, a two-week-old warthog living on the African savannah and who is growing fast.

Like most pigs, warthogs are not noted for their good looks; but what they lack in style, they make up for in character. Wally is part of a small warthog family and has several brothers and sisters.

Having spent the first few weeks of his life in the family's underground burrow, he is just about to venture out onto the dangerous African savannah. We follow him every step of the way as he explores the great outdoors.

He'll have to watch out for big bad lions, who would happily make a meal of a warthog his size. But not all animals are dangerous and he'll be made welcome by some.
