Again I am at a loss for words. Even Banana Street seems to make sense compared to the video below, which we found on Japan Probe.

All we know is that it's a commercial for elementary school "Randoseru" backpacks, and that the words the lady is shouting, "fuwarii" and "karuku," both mean "light.

Also, those backpacks? You can get one for $360. Three hundred sixty dollars.
