Nintendo of Europe's Satoru Shibata presents this little rap on the rules of their long-running action/adventure series, by way of Tomodachi Life.
I think it's safe to say that Tomodachi is working out pretty well for Nintendo, both in sales and harnessing the weirdness to tap into that latent internet love for... well, stuff like this. See also their post-E3 Tomodachi video.
For those unfamiliar with Shibata, well...
The guy's done some cosplay before, for the Nintendo of Europe sections of Nintendo Directs.
