Sisu
There is a movie called sisu. It's a pretty epic action movie. Worth a watch if you're into that kinda thing.
She want through a lot before she was born, hence the name https://en.m.wikipedia.org/wiki/Sisu
Is she a really strong swimmer?
Not really. It is raining atm, she refused to go out. Water is for drinking only.
Hehe, I'm spending too much movie time lately with my 5 year old. Sisu is the water dragon in Disney's Raya and the Last Dragon, and she constantly talks about her "power" being a very strong swimmer.
