Fluffy the fish v2

Thanks for saraapril telling me about "fluffy the fish v2" .
Fluffy the fish has second version. It's awesome! It has new look. There is penguin fishing in upper part.

There is also new ground.

You need eat fishes or little green balls to grow. You can only eat fishes smaller than you. To eat everything try to grow big as possible.

At the end of the level you can choose how you want to play next level. With mouse clicking, with mouse or with arrow keys.

After playing through some levels I saw something really weird. The big gray fish were afraid and swimming away from something.

There were no fish or green balls to eat. So I couldn't grow. I went there where was the thing that gray fish were afraid of. I saw big gray fish.

I don't know what to do, to continue. I try  to figure it out.
That's all for now.
