First appearance of the popular video game characters Bub and Bob
Bubble Bobble is the name of an arcade game by Taito, first released in 1986. It featured two cute dragons, Bub and Bob, who moved over a system of platforms, busting and pushing bubbles, avoiding bad guys and collecting a variety of power-ups. The game featured 100 levels, each with intriguing puzzles and twists.
Versions of the game were released for several home computer or game systems, including the Commodore 64, the Atari ST, and the Nintendo Entertainment System. A sequel to Bubble Bobble called Bubble Bobble 2 was also released for the NES, as well as Rainbow Islands, a sequel to the first two games. Rainbow Islands was later remade for the Sega Genesis.
Bubbles containing flames that, when the bubble is popped, drop downwards setting any surface they touch on fire for a short time, killing any monsters that touch the flame and turning them into 9000-point red diamonds.
Bubbling oneself through means "riding a bubble" through the opening at the top of a stage or even just through the ceiling of a stage in order to appear at the lower part, like some flying monsters can do.
BubbleBobble has been widely recognized as one of the most playable games of all time, owing much of its success to its previously described game mechanics, which are only apparently simple, and its many hidden features and secrets.
