Having raised a millennial, we had plenty of exposure to cartoons in the 90's and 00's. We were steeped in Dexter's Lab, Johnny Bravo, Spongebob, Rugrats and the like. But the one with the best theme song was The Powerpuff Girls (in fact it's still on my iPod). Builder legomichiiiiii built these lovely little ladies. Photo by willgalb.
