2 of 4: On not too crowded days, guests can enjoy seeing Pepe, a 5-month-old Humboldt penguin on the walkway at Brookfield Zoo's The Living Coast exhibit. By having Pepe serve as ambassador animal, Chicago Zoological Society staff hope to make a connection with the public that will inspire guests to want to learn more about Pepe's endangered counterparts in the wild.
