Penguins flocked together to catch some fresh snowfall in Pittsburgh, Pennsylvania. 

The penguins happily bounced through the door at the Pittsburgh Zoo and PPG Aquarium in an adorable penguin parade. 

The Penguins on Parade event is an annual event at the zoo, and people can see them on parade on Saturdays and Sundays unless it's too warm, the zoo says. 

Sometimes they get to parade around the aquarium for up to a half an hour!
