Plucking a duck:
> sy pluck Forms of syntax available for the command 'pluck': pluck <string> from <object> > pluck feather from duck You can't hold the feather so you drop it on the ground. You pluck feather from the proud black duck. > pluck feather from duck The duck shuffles away from you when you try to pluck a feather from him. > l duck This small black duck waddles around with his head held high. He is clearly an aristocrat of the duck world, with his long beak, deep black feathers and noble walk. He is in good shape. He is standing. The name "Ducky" can be seen on his collar. Wearing : a pet collar. Carrying: a duck feather.
So: the feather ended up in his inventory for some reason. After the first one I couldn't pluck any more, but maybe he resets eventually...?
