This diagram shows a state machine that we will need to implement to correctly
change the states and animations of the bunny head game object. It begins with an
overall check whether the feather power-up has been picked up (and is still active).
Then, subsequent checks will try to find out what the current animation state is to
take the correct actions accordingly.

To find out more about (finite) state machines like the one we used
in the preceding diagram, check out the wiki article at http://
