This is the Little Zoo That Could, always to be in the shadow of the bigger, more complete Phoenix Zoo. But this little west-side park is home to some species that that other zoo doesn't have ? namely penguins. You won't be much reminded of the amazing documentary March of the Penguins; the Wildlife World Zoo is home to only a handful, and they don't march miles in horrendous conditions to eat. They enjoy air-conditioned quarters and a steady supply of fish. But if you've just gotta see one in the flesh, it beats a trip to Antarctica.
