I bought a Ground Hog Micromaster, then later obtained the full set of the Race Track Patrol.
But I think I got a different version then I expected:
Original Ground Hog in the front, full set behind him.
This is the primary difference:
This feature is designed to let you swap parts of the figures between each other and presumably others of the product line.
But now I am wondering, given the difference, what did I actually receive?
