I didn't go to that museum, but i went to the one in Chania. The thing i remember most clearly is the little pull-along toy, substantially the same as one you might buy in a bougie toyshop today, that's getting on for three thousand years old:
Sorry if I'm just spreading factoids and platitudes, but isn't this the point at which some people say "it's not the wheel that was the hard part; it was the axle and bearings."? So a wheel for a child's toy would almost not even be a wheel.
I think you are confused with the idea "the romans invented the steam engine but only used it as a toy" which semi-misleadingly refers to the Aeolipile.
