Is there some way to pass level 570?

Hello everybody!

The game is becoming more and more difficult, of course, but some levels I can't think how to pass...

The level 570 we have to spread the jelly, but there's one square in the middle of the screen that I don't understand how I can get it. Even forming fishes they don't go there. It descourages me.

Please somebody can help me?

Thanks a lot
