- This article is about the specific variety of bubble. For the overall type of bubbles with special abilities, see Special Bubble.
The Special Bubble (スペシャルバブル Supesharu Babaru?) is a rare type of bubble appearing in several games in the Bubble Bobble series. When obtained, it replaces the player's bubble-blowing ability with a set number of fireballs that defeat enemies on contact, similar to the effects of a Cross of Fire. Special Bubbles are extremely rare in the games that they appear in, usually having a 1 in 4096 chance of appearing.
- The Special Bubble is also informally known as the "MTJ Ball", referencing Bubble Bobble creator Fukio Mitsuji's pseudonym while working at Taito.
