Puzzle Bobble (known as Bust-A-Move outside of Japan) is a spin-off of the Bubble Bobble series, featuring themes from the original game (such as enemies trapped in bubbles by the cutesy dinosaur duo Bub and Bob that must be popped). Players attempt to clear a board of colored bubbles by firing other bubbles at an angle and matching multiple bubbles of the same color. Its characteristically cute Japanese animation and music, along with its play mechanics and level designs, made it successful as an arcade title and spawned several sequels and ports to home gaming systems.
