Bubble Bobble

Bubble Bobble is a single-screen platform game where players control Bub and Bob, two characters transformed into dinosaurs. Their objective is to clear each stage of enemies to progress through a cave system.

The primary mechanic involves blowing bubbles, which can immobilize foes or act as temporary platforms. Defeated enemies turn into collectible point items. Certain bubbles contain power-ups like horizontal lightning attacks or downward-flowing water. A time limit on each level introduces Baron Von Blubba, a persistent enemy that appears if players linger too long.

Completion outcomes vary. A solo playthrough yields a bad ending, while a two-player campaign results in a good ending where the characters revert to human form. A secret code unlocks Super Bubble Bobble mode, featuring rearranged enemies and a true ending. Some versions offer additional content, such as extra stages or a hidden minigame with a different visual theme.
