 Numerous video games based on the series have been produced. Some of the early games include Legend of the Lost Spatula (2001) and SpongeBob SquarePants: Battle for Bikini Bottom (2003). The 2003 video game was added to the Greatest Hits by Sony. It also served as the engine basis for a video game based on the The SpongeBob SquarePants Movie. Heavy Iron Studios, the game's developers, tweaked the graphics to give the game a sharper and more imaginative look than that of Battle for Bikini Bottom. They also increased the polygon count, added several racing levels, and incorporated many of the creatures seen in the film. In 2013, Nickelodeon published and distributed SpongeBob Moves In, a freemium city-building game app developed by Kung Fu Factory for iOS.
