Puzzle Bobble 4 (also known as Bust-A-Move 4 for the North American and European console versions) is the third sequel to the video game Puzzle Bobble and is the final appearance of the series on the PlayStation and the only appearance of the series on the Dreamcast.

One day, the sun fails to rise because the Fairy of the Night, Cleon, has stolen the light source known as the Rainbow for Full-Moon Madame Luna.

Bub and Bob then set off to retrieve these bubbles and restore the light and peace to their planet.

This requires added strategy to prevent one side from moving too far and therefore losing the game.
