Bubble Trouble: Golly! Ghost! 2

Its gameplay is similar to its predecessor, instead being themed around sunken treasure. Players use the light guns to shoot at fish, crabs, seahorses, and other aquatic creatures at the bottom of the ocean. The four ghosts from the first game return as bonus enemies that can be shot for additional points. Bubble Trouble makes usage of sprite-scaling effects to make enemies fly towards the player.

Like its predecessor, this game uses an electro-mechanical diorama for its background, with movable parts powered by solenoids. A mirror inside the machine reflects the game's graphics onto the background, creating the illusion that the characters are interacting directly with the diorama.
