And that is certainly what visitors and staff at Edinburgh Zoo are celebrating following the arrival of three Northern Rockhopper penguin chicks this week.
The hatchlings are just a few days old, and as the video shows at the top of this article, they've taken their new surroundings like a penguin to water.
They are expected to nest with their parents until they reach around three months old.
Edinburgh Zoo announced the new arrivals on Facebook, saying: "What better way to mark #WorldPenguinDay than to announce the arrival of 3 Northern rockhopper penguin chicks!
"Only days old, the chicks will remain on the nests with their parents until they reach around 3 months.
"Northern rockhopper populations are declining in the wild and we hope these chicks will play a part in raising awareness about the threats they face from pollution, hunting and climate change."
