A sequel to "Balloon Fight" called "Balloon Kid" was released in October 1990 in North America and on January 31, 1991 in Europe for the Game Boy, which expands from the game's roots and revamped it into a full platforming adventure. This title was not released in Japan on the Game Boy, but colorized versions titled as "Hello Kitty World" (published by "Character Soft") for the Famicom and "Balloon Fight GB" for the Game Boy Color were later released only in Japan.
