Monsta (もんすた Monsuta?), also known as Beluga or Blubba, is a recurring enemy in the Bubble Bobble series. One of the most common enemies in the series, Monstas appear in nearly every single Bubble Bobble game, and have a recurring role as a playable character in the Bust-A-Move games.

Biography Edit

Appearance Edit

Monstas resemble round purple whale-like creatures, sporting a small tail and two fins on either side of their body. They are generally depicted as having red eyes and wide mouths. Bubble Memories features a green variant of the Monsta with yellow eyes, but the two behave functionally identical to one another.


Monstas do not have many abilities outside of being able to fly. They generally cruise around the stage, changing trajectory upon bumping into walls. The Monstas appearing in Rainbow Islands are able to fire out a spread of six small Skel-Monstas at the player, an ability which has not returned in any other game since.


Chack'n PopEdit

Monstas first appear in Chack'n Pop, first appearing in the opening cutscene, stealing the Hearts from Chack'n and Miss Chack'n. They are the most common enemies, attacking by flying around the level and attempting to hit the player. Monstas hatch from eggs that are hanging from the ceiling.

Bubble BobbleEdit

Monstas reappear in Bubble Bobble, behaving similarly to their appearance in Chack'n Pop. They fly around blindly, bouncing off of walls and attempting to hit the player. Two Giant Monstas appear on Round 64, carrying Betty and Patty to the bottom level of the Cave of Monsters.

An invincible skeletal Monsta known as Skel-Monsta also appears, showing up if the player takes too long to complete a level.

Rainbow IslandsEdit

Monstas return as enemies in Rainbow Islands, appearing in the game's final world, Bubble Island. The Monstas encountered in this title have the ability to fire a spread of six projectiles shaped like small Skel-Monstas.

Parasol StarsEdit

Monstas appear exclusively in the Underworld in Parasol Stars. They act identically to their appearance in Bubble Bobble, but appear significantly larger than other portrayals, and have yellow eyes instead of red ones.

Bubble Bobble Part 2Edit

Monstas reappear in Bubble Bobble Part 2, behaving identically to their appearance in Bubble Bobble. Later levels of the game feature Monstas with white sheets covering them known as Ghost Monstas. The sheets can be knocked off by a single bubble, turning the enemies back into regular Monstas. The Monstas in this game have yellow eyes, similar to their appearance in Parasol Stars.

In the North American manual for Bubble Bobble Part 2, Monstas are known as Slider.
