Pesto (hatched 30 January 2024) is a king penguin living in Sea Life Melbourne Aquarium who gained notability in September 2024 due to his exceptionally large size during his infancy.

[6] This decision was made in part due to Blake's age (22 years), and Tango and Hudson's lack of success in hatching their own eggs.

[9] At the time of his gender reveal in September 2024, which was broadcast on social media,[6] he weighed 21 kilograms (46 lb),[10] making him the largest king penguin chick to ever live at the aquarium.

At that time, Pesto was reported to have lost around 10 kilograms (22 lb) of weight compared to before his shedding, and to have developed a close relationship with a female penguin named Pudding.

[17] On 9 October, a mural depicting Pesto surrounded by four much smaller adult penguins was unveiled in the Melbourne central business district.
