Bubble Bobble Wiki

Pulpul (ぷるぷる Purupuru?), also known as Hullaballoon or Boa-Boa, is a recurring enemy in the Bubble Bobble series. First appearing in the original Bubble Bobble, Pulpuls have appeared in nearly every subsequent mainline Bubble Bobble game since, as well as occasionally being featured as a playable character in the Puzzle Bobble series.



Pulpuls are peach-colored creatures with four limbs, each with a round yellow appendage at the end. They have a purple propeller affixed atop their heads, which they use to fly.


Pulpuls use the propeller atop their head to fly, taking advantage of their aerial positioning to attack foes. The Pulpuls appearing in the Rainbow Islands series are able to drop bombs, an ability yet to appear in the main Bubble Bobble series.
