Robert Irwin announced in Queensland that Prince George, Princess Charlotte and Prince Louis chose the Welsh word, meaning cuddle, for the eastern grey joey.
The joint Instagram post said the naming aimed to spotlight conservation, with Irwin thanking the family for backing efforts to protect kangaroos and other wildlife.
The event also highlights Prince William's wider environmental work through Earthshot, as eastern grey kangaroos face threats from habitat loss, climate change and human activity.
