Wii Street U has perhaps been forgotten a little since its initial arrival as a free download in early 2013, though the fact it was a freebie helped to make it the most downloaded Wii U eShop title ever in some regions — Google really is taking over the world.

It's a neat app, nevertheless, and is useful as a means of showing off the GamePad as a 'window' into the world.

Nintendo isn't quite finished with it, as it's kicked a treasure hunt / challenge in the app via Miiverse. You can see some details from Toshiaki Suzuki below.
