Have you seen the movie Dug. Its great.
They have an AA type association for sharks that are not going to eat other fish anymore (shades of DW and the teatotal vampires).
And Dory (played by Ellen Degenerese) has a saying that I love :Just keep swimming Just keep swimming. A saying we still use when you have something to get through or things are grinding you down.
My favourite song of all time is sung at the end of it by Robbie Williams "Sur De Mere"
