Baby Boomer decided to leave his crib and set out for the dangerous wilderness outside of his house.
As Boomer crawls across the screen toward numerous dangers, such as birds of prey and bottomless pits, the player uses his/her NES Zapper to shoot hazards before they hurt Boomer. Shooting birds kills them; shooting clouds makes them form ice bridges over pits. Level environments include a graveyard, the "Pearly Gates" of heaven, and even the pits of hell. Up to two players can participate simultaneously and use the basic NES controller along with the Zapper.
This game was Color Dreams' first game. Like their other unlicensed games, rather than the typical grey NES cartridge, Baby Boomer is baby blue with an altered design.
