★An endearing and very positive fable about the importance to live and value the many good things of everyday life.

Casildo the rooster has problems. He’s been unemployed for three years, he owes six months’ rent and the only job he’s been offered is giving singing lessons to a group of centenary turtles: the Wonderfuls. But if the turtles can’t sing, what will people say about him who used to be one of the great opera singers of the past?

They are retired and very old, but their optimism is indestructible. They want to win a musical contest to give the prize to a charitable cause... Although everyone knows that turtles can’t sing, don’t they?

She often cycles through the city and eats surprising amounts of ice cream.
