Impossible Pack

The Impossible Pack is the tenth and final downloadable course pack for the Coin Rush mode of New Super Mario Bros. 2, released along with the Mystery Adventures Pack on December 20, 2012. The difficulty rating is labeled "DANGER!". The courses are centered around high amounts of near-impossible challenge. In a twist, there are no coins in any of the courses in this pack; players instead earn coins based upon the time remaining at the end of each stage, hence the 100 coin target. The courses also contain no power-ups; if the player has a Gold Flower in their inventory at the start, they may not access it.

Course 1
The first portion of the course is a beach-themed area. The course begins with an underwater segment with several Spiny Cheep-Cheeps and a Porcu-Puffer. Afterward, there are two whirlpools with a Cheep-Chomp.

Through the pipe at the end is a sky level. The player traverses by standing on a rotating platform, that moves depending on where Mario is positioned. Crobers attempt to attack him. After the Midway Flag, there are pipes which drop Bob-ombs onto the platform. After this is a pair of Lakitus which rapidly drop Spinies. The pipe leading to the next area is a distance away from where the platform stops.

The next section is another beach area, with several Hammer Bros. and a pair of Chain Chomps before the Flagpole.
