Soooo... what you're saying is all that's needed is a few note blocks around the bird's face and you've got yourself a singing duck?
In fact, Peter, go the whole hog and make it sing "White Christmas".
Then I'll be happy. :-P
That duck looks huge, if you're going to be building your song ducks on that scale, how big is the car park going be, not to mention the whole bio-dome project, is 450x450 blocks going to be big enough?
