Timmy has out-flippered Mo to become the National Aquarium of New Zealand's first ever Penguin of the Year.
It was a battle of the "bad boys" - Timmy is famous for his fish stealing feats, while Mo, abandoned as a chick, also has a thing for stealing fish.
Between October 1 and 28, more than 10,700 votes from all over the world were cast before Timmy was crowned the winner. They came places as far as Guatemala, Estonia, Iran, Belarus, Vietnam, Singapore, Peru, China, India, Canada, the US, UK and Australia.
Comments on social media included: "there's a little bit of Timmy in all of us".
