A third African penguin chick has hatched, joining playmates Oscar and Duffy, who were born in December.
The aquarium is celebrating its newest arrival to the colony with a naming contest.
The choices are: Scrappy, Zero, Flounder, or Toothless.
Guests can vote in person only for their favorite name through donation boxes at the aquarium.
The contest is open through January 19.
The winning name will be announced on January 20, which is Penguin Awareness Day.
