At Melbourne’s Sea Life Aquarium, one penguin is standing out among the flock. Pesto, a nine-month-old king penguin, has gone viral due to his unique appearance and immense size. Weighing a staggering 22.5kg (50lb) and covered in chocolate-brown baby fluff, Pesto towers over his foster parents, Tango and Hudson, at the aquarium.

A Viral Phenomenon
Pesto’s rise to fame has been swift, captivating millions worldwide. His viral popularity extends across social media platforms and international TV, with pop star Katy Perry among his fans. With an audience of nearly 5 billion people, he has become a global sensation, attracting visitors to the aquarium from around the globe.

Healthy and Growing
Though he’s affectionately referred to as “fatty” and an “absolute unit,” Pesto’s considerable size is attributed to a healthy appetite—eating up to 30 fish a day. According to marine biologist Jacinta Early, Pesto is well cared for and will naturally slim down once he loses his baby feathers. Described as a social and playful character, he enjoys interacting with both humans and fellow penguins.

A Star with Staying Power
Despite the aquarium’s typical busy season, visitors have been flocking to see Pesto. His media manager, Olivia Wilson, has juggled numerous interview requests for the famous penguin, who may even rival the Australian Football League grand final in popularity this weekend. Pesto’s global reach has surpassed that of other internet-famous animals, such as Thailand’s baby pygmy hippo.
