Why can I not override Animal.noise just like I override Animal.sound, via creating a new method in the class to overide

Is there a reason why def noise(self) here is not working? def sound(self) did work in its override...

sheep.py 
from animal import Animal

class Sheep(Animal):
  pass

  def sound(self):
    self.sound='BLaaa'

  def noise(self):
    self.noise=self.sound.upper()

You should be changing the sound attribute in the class, not providing a sound() method (that that passes shows me I need to add another check to the challenge. Thanks for finding that!). Finally, in noise(), you need to return the uppercased version of the sound. What you're doing now is changing the method to an attribute...sorta. It's just erroring out due to that being invalid code.
