Puzzle Bobble Plus!

In each stage, players aim the cannon (helmed by Bubble Bobble's Bub and Bob) at the bottom of the screen, using it to shoot differently colored bubbles at a hanging arrangement of bubbles at the top of the screen in order to make them disappear within a time limit. Players must match three bubbles of the same color in order to get rid of them, with each stage being completed when all the bubbles have been cleared. (wiki)
