CAMDEN, N.J. (CBS) - Blue for a boy.... pink for a girl.
Cakes with colored filling inside are all the rage nowadays to announce a baby is on their way, but one gender reveal party Thursday had a bit of a twist.
It's not every day one is held for a penguin, let alone a new born that is more than four months old like Topper.
But at Adventure Aquarium in Camden the cake was cut ...with pink filling.
Biologist Kate Budion says when penguins are born, it's not known if they are male or female:
"We wait a few months until they are not really baby birds anymore. So we wait until they are juveniles, our vet comes in, takes a blood sample, we actually send it away to a lab to get DNA tested, they send us back the results to let us know if it's a boy or a girl."
African penguins are endangered in the wild and Topper is a part of a species survival breeding program.
You can see Topper and the entire penguin colony waddling around on the Aquarium's Penguin Island.
