Penguins at UK’s Edinburgh Zoo had great fun chasing after and popping colorful bubbles to celebrate the Penguin Awareness Day on Saturday. /Edinburgh Zoo Photo

The bubbles were created by a bubble machine newly gifted to the Edinburgh Zoo as a Christmas present to the birds. From water slide to floating platforms, penguins enjoy a variety of enrichments at the zoo. /Edinburgh Zoo Photo
