Thousands of penguins. Anyway, they have the real cold weather types in an icehouse and they go out and dive and fly underwater and so forth ~ and POOP A TREMENDOUS AMOUNT ~ they eat only fish.
Be thankful your daughter didn't get into collecting real penguins.
I think that facility was just getting going when I was a child in San Diego, early 70s. My daughter got into penguins when the Tulsa Zoo got them, when she was about 2. They do poop a lot!
