A king penguin chick named Pesto, weighing 22 kg at 9 months old, has become a social media sensation and star at Sea Life Melbourne Aquarium. Pesto, heavier than his parents Hudson and Tango who each weigh 11 kg, has been viewed by over 1.9 billion people globally. He consumed 24 kg of fish in a week, which is healthy for his age. As he enters his fledging period, Pesto will lose his brown feathers for adult plumage and slim down to around 15 kg. His keepers expect him to remain a TikTok celebrity for another two weeks.
