You say that like it has an understanding. If I could have forked the conversation after it gave a unicorn I would have, but I was able to start my own and ask for ASCII art of a parrot. On the first try it gave me a sitting penguin (probably Tux art from the training data)
When I then asked it if the image was really a parrot it told me that it was "more of a generic 'ASCII bird' (often used as a generic owl/parrot placeholder), not a true parrot."
A sitting penguin is certainly not a generic bird.
