Penguin has been part of the Bloom family in Newport, Sydney, since 2013, after 11-year-old Noah found her abandoned on the ground when she was only a few weeks old.
Noah brought Penguin home to his family - Cameron and Sam and brothers Rueben, 13, and Oli, nine – and the bird, whose species is known for their intelligence, has fitted right in.
Dad Cameron told Daily Mail Australia: "We kept her because I felt confident that I had the time and knowledge to bring her up safely and healthily.
"My best friend is also a vet. Her diet was meticulously made so she had the right balance. It used to take me half an hour to mix it all together."
The dad added: "The kids love her like a pet dog and it's just become so normal having her around.
"She likes to sing for us when she's around the house and likes to fly onto your head or sit next to you and nibble on your ear.
"She usually has some of our scraps but sometimes when we have spaghetti, she's cheeky and dives into to grab some of the meat off the table."
Cameron, a professional photographer, has documented the moments his family has shared with Penguin and posted them on Instagram, which has more than 3,000 followers.
He said: "The joy she's bought to all our lives has been immeasurable."
