A group of Magellanic penguins at the Philadelphia Zoo is taking summer fun to a whole new level.
The black-and-white birds were recently caught on video lining up along the rocks of their enclosure before taking turns diving into the water below.
The first penguin carefully approaches the edge, looks down and finally takes the plunge.
Once that brave bird goes for it, the rest of the group quickly follows.
The Philadelphia Zoo shared the adorable footage as the penguins explored their outdoor habitat at Hollenstein Ross Penguin Point.
“Our new colony of Magellanic penguins is diving, swimming and splashing through their outdoor habitat at Hollenstein Ross Penguin Point!” the zoo wrote.
Judging by the video, the colony seems more than comfortable in its new surroundings.

Viewers online couldn’t get enough of the tiny cliff divers.
“I actually caught myself going ‘weeee!’ out loud when the first penguin jumped,” one person commented.
The reaction makes sense. Despite standing only around 2 feet tall, Magellanic penguins are impressive swimmers.
Penguins are flightless birds, meaning they don’t take to the skies like most other bird species. Instead, they have evolved into powerful swimmers built for life in and around the water.
Magellanic penguins can swim at impressive speeds and dive deep beneath the surface while hunting for fish.
In the wild, they often live and breed around rocky coastal areas, so jumping from rocks into the water is completely natural behavior.
Penguins have also been observed gathering in groups near the water before one brave bird goes first.
Once the first penguin decides the coast is clear, the rest often follow.
That certainly appeared to be the case at the Philadelphia Zoo, where one adventurous little penguin kicked off what quickly turned into an adorable pool party.
