Next thing to try to resolve:

Traceback (most recent call last):
  File "./hugs.py", line 55, in <module>
    class RunnerSprite(MotionMixin, CircularRegion, ppb.Sprite):
  File "./hugs.py", line 60, in RunnerSprite
    image_scared = Emoji('scared')
  File "/usr/home/puppy/dev/astronouth7303/mutant-games/venv/lib/python3.7/site-packages/ppb_mutant/__init__.py", line 140, in __init__
    super().__init__(_resolve_name(self.shortcode, self.morph, self.tone))
