.. Getting rid of the owl

You need a replacement owl, or a bird.

There is another bird around here.

In the kitchen. The nightingale.

But it doesn't really look like an owl.

It is not even the same color.

Make it black. ( There are coals in the cellar. Use the bird on the coals. )

Great, go swap it to the owl.

Hmm... It is making sounds, still... You should stash it somewhere safe.

Put it into the cage in the kitchen. Where you took the nightingale.
