Il Coccodrillo come fa?

Hehe, I hope I will always remember this song. Stefania and Gaitana sing it to Riccardo all the time. They'll ask him at dinner, "Riccardo, come fa il pesce?" or "Come fa il gatto?" like we would ask What does a fish do? or What does the cat say?

So, this song is about the crocodile.

'What does he do? There isn't anyone who knows. One says he eats too much...'

'Il coccodrillo come fa? Non c'e' nessuno che lo sa. Si dice mangi troppo...' (and I don't know the rest yet, and I want to figure it out without looking up the lyrics)
