基础版
Hello, everyone! I'm Willy, a blue whale. I'm proud to be the biggest and heaviest animal on Earth. Can you believe I can weigh up to 200 tons That's like having hundreds of cars stacked together!
I swim freely in all the oceans around the world, except for the freezing Arctic Ocean. The water there is just too cold for me. My home is full of amazing creatures, and I especially love feasting on the tiniest animals in the ocean. Every day, I eat around four tons of them to keep my big body going.
Even though I'm huge, I love moving through the water. The ocean is my playground, and I enjoy showing off my swimming skills. I hope people will keep our ocean clean so that I and all my friends can live happily here forever.
