The new Nintendo Direct Mini isn't about the Wii Mini. It's about new/old New Super Mario Bros. 2 levels that are temporarily free on the Nintendo 3DS. Not too confusing, right?

Skip to 3:50 to see the levels. They may ring some bells.

UPDATE: So... the 3DS eShop appears to be offline for maintenance now. Bad timing. It'll be back at 8pm ET or so.
