In the video that was published by the official account of Shedd Aquarium, we can see Wellington — a penguin that took a walk to see some fish from the Amazon.

"Penguins in the Amazon? Some penguins went for a walk to meet other animals. Wellington seems more interested in the fish in the Amazon Rising. Disk tetra also seems interested in this unusual visitor," they said in the post.

The goal of allowing animals to freely walk inside the aquarium is to keep them active. According to CNN, these activities will be done to try food they can, and for them to learn to behave in a more natural way within the aquarium environment.
