Four lion cubs will be joining their mum in an outdoor home that's surrounded by water - so it's time they learnt how to swim!
The eight-week-old cubs live in Smithsonian's National Zoo in Washington DC, America, and went for their first swim to test how well they do in the water.
To start off with, zoo keepers placed the one male and three female cubs into the water, one after another.....
And then checked whether the cubs would be able to move around safely if they take a dip - or fall - into the water that surrounds their new home.
Good news - all four passed their first swimming test!
They kept their heads above water and three of them were able to find their own way out onto dry land...
... but one little lion needed a bit of help. The zoo staff were always nearby to give a helping hand whenever it was needed.
Despite doing so well, the zoo says it will probably install some ramps from the water to the land to make it easier for the cubs to climb out. Well done guys!
