Pre-order New Super Mario Bros. 2 at GAME or Gamestation and you'll be awarded a collectible gold coin case.
The coin case is shaped like the shiny circular currency of the Mushroom Kingdom.
New Super Mario Bros. 2 will feature a new focus on collecting these coins. It will hit UK shop shelves on 17th August.
Nintendo claims the case is "a handy accessory if you're always on the move".
"The small case - a replica of Mario's iconic Coins - can hold any number of small objects including the New Super Mario Bros. 2 Nintendo 3DS Game Card itself," a statement from Nintendo read.
And, as with the gold-coloured Zelda: Skyward Sword Wii Remote, Nintendo's usual disclaimer: "Please note that the New Super Mario Bros. 2 collectable gold coin case is gold-coloured only and does not contain any real gold."
Just in case you were wondering.
