All of Ella's mates are really proud of her new swimming stroke and they're all keen to make a splash with it.
It all came about when Ella entered a Swim4Life competition.
Can Leah win the Dolphinella race?
Organisers want to get children fit and healthy while still having fun. They asked kids to come up with new ways to swim.
Ella's stroke proved the most popular. She received more than a 1,000 votes and won a trip to Alton Towers water park. And I presented her with a certificate for her efforts too.
At the moment there are no plans for schools to teach this new stroke in swimming lessons but Ella's really keen that one day is could feature at the Olympics with swimmers like Michael Phelps or Rebecca Adlington winning gold doing the Dolphinella!"
