Nurdle Durdles

My kid is obsessed with this Aquafresh commercial. It comes on every night at 7:58 (just after Caillou) on Sprout and has become part of our nightly ritual. I finally caught a vid of Lucy doing the dance, which for some stupid reason they call The Nurdle Durdle. I don't really see what that has to do with toothpaste, but... I guess its pretty cute.
