How to control more than one image position with Kivy

Question

I am making a game with Kivy where you can move a character around the screen. Earlier, I had it working where when you move the character right, the background image would scroll to the left, and same with the right. Recently, what I tried to do was add the background image to a widget along with another image, with the intention that i could control multiple image locations with 'widget.pos', but as soon as I did this, not only does the second image (hero2) not scroll right or left but neither does the background image. I am wondering what I did wrong in my code here.

from kivy.app import App
from kivy.uix.widget import Widget
from kivy.uix.image import Image
from kivy.core.window import Window
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.uix.label import Label
from kivy.uix.behaviors import ButtonBehavior
from kivy.core.audio import SoundLoader
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.gridlayout import GridLayout
from kivy.uix.screenmanager import FallOutTransition


gamelayout = FloatLayout(size=(300, 300))


class Game(Screen):
    pass    


class IconButton(ButtonBehavior, Image):
    pass

class Bg(Image):

    def __init__(self, **kwargs):
        super(Bg, self).__init__(**kwargs)
        self.allow_stretch = True
        self.size_hint = (None, None)
        self.size = (1440, 1440)

class MoveableImage(Image):

    def __init__(self, **kwargs):

        self._keyboard.bind(on_key_up=self.on_keyboard_up)
        self.size_hint = (.11, .11)
