Hey vincent300985 (and others),
Be careful, there is another product that is kind of misleading and it is
not the
Morph 2x2x1 head. It is a soft plastic action figure that comes with a "puzzle accessory", (other action figures also come with other parts of the "puzzle"). The final "puzzle" might be B.E.N. the robot (or not, see edit below).
Skarabajo.
EDIT: Actually, I'm not sure anymore about the "puzzle accessories" becoming the robot. I saw other pictures and there is a possibility that all eight action figures had a "puzzle accessory" that would create something else... Maybe the "map ball"? In any case, this McDonald's happy meal collection does not include any twisty puzzles. Also, this McDonald's happy meal collection was distributed in Canada and in the US in 2002, the other McDonald's happy meal collection (the one with the Morph 2x2x1 head) was distributed in Europe/Asia in 2002-2003.
