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.
