Class methods question from the video: Attribute error

I replicated this error in both my Workspace and my own terminal:

>>> jubjub = Monster()
>>> jubjub.battlecry()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'Monster' object has no attribute 'battlecry'
>>>

Here is the code:

class Monster:
    hit_points = 1
    color = 'yellow'
    weapon = 'sword'
    sound = 'roar'

def battlecry(self):
  return self.sound.upper()

def battlecry(self):
        return self.sound.upper()

was not properly indented.

It passes with no error.

This is my code:

class Monster(object):
    hit_points = 1
    color = "orange"
    weapon = "gun"
    sound = "roar"

    def battlecry(self):
        return self.sound.upper()

And although I idented correctly, nothing changed. Why? I am using Python 2.7.
