Funny World & Balloon Boy is an unlicensed two-in-one cartridge containing two simple games.
The story revolves around a boy and a strange creature known as Funny World , where the player must shoot various funny animals that cross the screen. The goal is to hit a set number of funnys before they reach the other side, while avoiding female funnys that will cause the player to lose a life. The player also has boulders at their disposal to hit funnys out of range.
The gameplay in Balloon Boy is similar, where the player controls a boy at the bottom of the screen and must shoot balloons floating across the top. The player must collect items released by shot balloons while avoiding deadly traps. If all balloons are destroyed before time runs out, the player progresses to the next stage.
Funny World & Balloon Boy was released for the Sega Genesis in 1993.
