So, I've had these two duplicate sets of McToran/Tohunga/Flexarm McDiskshoot Kongu for quite some time now, and I've noticed something odd. They do not have the same packaging. At least, not in the text department. One of them has the McDonald's logo in all its glory, but the other does not. The one with the logo is labeled as "4+", while the other is labeled as "7+". They both seem to have the map of Mata Nui erroneously labeled as "Ga-Koro" for some reason. One says 2001, while the other 2002.

So there is definitely a difference in packaging, as you can plainly see. But what does this mean? They were apparently released in two separate years, so was it released outside of a promotional item?
