“Brutal Floating Behemoth,” The second MOAB-Class Bloon that you encounter in BTD6. It appears on Round 60 and is the final boss of Medium Difficulty. It pops into 4 MOABs when defeated. The BFB has 700 health, (1400 when Fortified,) and moves at a relatively slow speed giving you plenty of time to pop it.
I love BFB

BFB stands for best fucking bitch. That ride or die best friend. That best friend who you can tell anything to. Call her up and tell her you need to move a body and she'd be there like yesterday. An amazing girl who's out of this world awesome! She's got your back when no one else does.
"Crystal you're my bfb."
"Girl you're a bfb."
"You're a ride or die bitch like a bfb."
