(CNN) The penguins at the Shedd Aquarium in Chicago are usually the ones being looked at, since they are one of the most beloved attractions. But Sunday, they were able to get a taste of what it's like on the other side of the glass.

With the building closed to visitors to help prevent the spread of the novel coronavirus , a group of rockhopper penguins were allowed to leave their habitat and explore the rest of the aquarium.

"Without guests in the building, caretakers are getting creative in how they provide enrichment to animals," the aquarium told the Chicago Tribune . "Introducing new experiences, activities, foods and more to keep them active, encourage them to explore, problem-solve and express natural behaviors."

The aquarium posted to Twitter a video of one of the penguins, named Wellington, meeting some fish in the Amazon exhibit.
