CAMDEN, N.J. (WPVI) -- Camden's Adventure Aquarium has reason to celebrate.
Thursday, officials revealed that their newest African penguin chick, Topper, is a girl.
African penguins look identical, and their gender, can only be determined by a DNA blood test.
After the big announcement, Topper celebrated with pink toys, and a special pink cake.
She is now on exhibit, with the rest of the penguins, just in time for Mother's Day weekend.
