So for you all who collect MOTUC... do you mix and match from other lines? Be it animals, vehicles and even playsets or do you stick to all of one line and era in your collecting? I have gotten into this line and thank God I don't desire everything but I am big on animals, playsets and even vehicles. I know Mattel has made a lot of these in the sub line but not nearly everything so I was curious who out there mixes and matches in their collections?
