And now for something, completely different! This is so much more than the expected BrickHeadz MOC construction toolkit.  It lets you build not one, but two full figures (and the second needn't be a ghost as shown above), it has a rather long and detailed instruction manual, and it provides a hefty serving of varied pieces at one of the lowest price/part ratios of all time.
