Bubbles (アワ Awa?) are the main gameplay mechanic in the Bubble Bobble series. Bubbles are most often produced by the player character, and are utilized to trap enemies within them. The enemy will be defeated after the bubble is popped, leaving behind a food item. The player is also able to jump off of bubbles, using them as platforms. In addition to bubbles created by the player, they also spawn naturally on some levels, usually rising up from gaps in the bottom of the stage, following the air current of the current round.
