Super Mario 3D World is a platform video game in the Super Mario series developed and published by Nintendo for the Wii U home video game console in November 2013. It is the sixth original 3D platform game in the series and the sequel to the 2011 Nintendo 3DS game Super Mario 3D Land. The game follows Mario and friends attempting to rescue fairy-like creatures called Sprixies from Bowser, who invades the realm known as the Sprixie Kingdom. The gameplay is similar to previous installments of the series, with players passing through individual levels to reach Bowser. The game features a character selector as well as introducing a power-up called the Super Bell, which turns the player into a cat, enabling them to climb walls and use a scratch attack.
