It makes use of the wireless capabilities of the DS system to see various WiFi hotspots (SSIDs) as players approach them in the real world. Each hotspot gives players stardust (which is used to complete the game), gear to customize your on-screen avatar, or an actual treasure piece. Each piece of treasure makes its own sound and represents some real-world object. Players can arrange these pieces in their play area and create a song, ala Mario Paint.'
