Well, if you are going to spare us from reading all of your code,
you'll have to debug it yourself. The clue that Fredrik gave you is
*not* of the use-once-and-discard variety -- when you are having
problems with the pixies changing your lists into strings, you need to
sprinkle prints of type(pixie_prey) and repr(pixie_prey) at salient
points in your code; as first statement in that __init__ method would
be a good start.
