In the eShop. It's about 570MB and features 3 levels. It features that Black Betty stage, a stage where you float in the air via wind, and a stage where you use the touch screen on the GamePad while the character on the screen moves by itself. Honestly, the Black Betty stage is alright, it's just really short and really easy. The Touch Screen level was surprisingly fun, because even though the character moved by himself, you'd actually have to stop enemies, or cut rope and move platforms.
