B.F.B.

 The B.F.B. ( B ald F latulent B limp) was a prototype version of the better-known Brutal Floating Behemoth. It has 7,000 HP and moves at a fifth of the speed of a Red Bloon's. It has a 3% chance of spawning (only from natural spawns, not from ZOMGs or other BFB carriers) instead of a normal B.F.B. (assuming the player is on freeplay mode). But is this all? No it isn't. The blimp is called Bald Flatulent Blimp for a reason. It has these abilities:
 * Flatulence: The propulsors make a little burst, moving the B.F.B. by 70px. Any tower caught in it will suffer 6 HP damage and will get stunned by 10 seconds, druing which time they will be coughing from the smell.
 * Mega Flatulence: The propulsors make a little burst, moving the B.F.B. by 150px. Any tower caught in it will suffer 13 HP damage and will get stunned by 10 seconds, druing which time they will be coughing from the smell.
 * Ahhh... (Passive): Gains 25 HP per frame while being attacked by a bad-smelling tower or special agent (such as Mutant Monkey or Bloon-a-site Monkey). Also affected by Onion Flatulence.
 * Onion Flatulence: Charges up to 5 seconds, then causes a huge bad-smelling explosion that poisons every tower in it by 1 second (note that the poison will keep applying while the tower is in the stench cloud), dealing 2 HP damage every second, and stunning them too, by 1 second (see previous parenthesis). Note that this also causes Ahhh... to trigger. The burts is 250px in diameter.
 * Bald Reflection: A bright beam of sunlight reflects on the BFB's center, reflecting it towards a random direction, the light beam will stay active for 3 seconds before disappearing. Any towers within the light beam cannot attack and take 10 HP damage from the sudden sunlight beam.
