Bubble Bobble II (c) 1994 Taito.
Eight years since the introduction of the renowned puzzle maze game comes this upgraded reincarnation with more excitement.
The first direct sequel to Taito's 1986 classic, 'Bubble Bobble' - the first ACTUAL sequel was 1987's 'Rainbow Islands', which played very differently to Bubble Bobble - in which one or two players take on the role of the infamous bubble-blowing dinosaurs (selected from the four available; Bubblun, Bobblun, Cururun, and Cororon), each of which possesses its own individual game-play attributes; such as faster bubbles or larger bubbles etc.). The players must once again fight their way through a large number of single-screen platform-based levels, trapping monsters with their bubbles before bursting them to destroy the trapped enemies. Bubble Bobble II's game play is identical to that of the original game, although new bonuses and weapons have been introduced to breath new life into this timeless game. One new addition to the game-play is the introduction of 'Multiple Bubbles'; if the player holds the button down for a few seconds before releasing; up to three bubbles are produced at once.
The game's graphics are, of course, a vast improvement over the original; with lush, colorfully rendered backgrounds and detailed, smoothly animated sprites doing full justice to the legendary video game characters. Bubble Bobble II features cameo appearances by a number of characters from many other Taito games. The game also features multiple endings, depending on the skill of the player and on secrets found.

>>> TRIVIA
----------
Released in October 1994.
This game is also known as 'Bubble Symphony'. Though the game was sold for home systems as 'Bubble Bobble II', Bubble Symphony is unofficially Bubble Bobble 4, since three earlier arcade games featuring the same characters exist (more if the 'Puzzle Bobble' series is included). It could even be called 'Bubble Bobble V', since a cartridge for the NES/Famicom exists called 'Bubble Bobble 2'.
In the attract mode title sequence, Bubblun appears in front of a closed red curtain (which will turn blue if the 'Game Mode Select' code is entered) announcing, 'Ladies and Gentlemen, this is... Bubble Bobble II!' The curtain then opens on the cast of enemies as follows :
* Bottom row (left to right) : Flhoop, Uni Bo, Drunk, Banebou, Invader, Zen-Chan, Mighta, Rappappa, Catch Maru, Roboj, Hattonton
* 2nd row from bottom (left to right) : Monsta, Komso, Kabukky, Mya-Ta, Heita-Kun, Warurin, Hidegonsu, No-No, Upper, Ame Da-Ma, PulPul
* 2nd row from top (left to right) : Robol, Rocketl, Yuki-Bombo, Mummy, Chu-Chu Man, Jiji Poppo, Kiri Kabu Kun, Bolt Man, Strong Shell
* Top row (left to right) : Dorabo, Ouji Sama, Knightron, Dranko, Magician, Denkyu-Kun, Ankororin

In the closing credits, PulPul's name is listed as 'Puru Puru'.
The enemy known as 'Catch Maru' can be seen in two different color schemes : one with a blue robe and purple shoes (as seen in the attract mode title sequence), and one with a green robe and blue shoes.
The game forbids the initials 'SEX' on the high score table. If you try, it gets changed to 'H !'.
There are a grand total of 164 rooms in the game, including 18 boss rooms.
