You don't use 'target' anywhere...

IIRC, __new__ is supposed to return the newly created object - which you
are not doing here.
class Bar(Foo):
def __new__(cls, a, b, c, *args):
print 'Bar.__new__', len(args)
if not args:
cls = Zoo
obj = super(Bar, cls).__new__(cls, a, b, c, *args)
if not args:
obj.__init__(a, b, c, 7)
return obj
