Chocolate-brown and fluffy, Pesto is a 9-month-old king penguin that weighs 52 pounds, more than twice the combined weight of his parents. He has drawn hundreds of visitors to an Australian aquarium and now the bird can count Katy Perry as one of his biggest fans.

Pesto the penguin has taken over the internet as the fluffy baby is capturing hearts. The new social media celebrity has become a star attraction at an Australian aquarium. The king penguin chick went viral for the unusually enormous size and has been racking up views online.

In late January, caretakers at Sea Life Melbourne Aquarium in Australia were ecstatic when a king penguin chick successfully emerged from his shell. The baby, which they named Pesto, was the only king penguin born at the aquarium in the last two years.
