Foo Fighters, Part 2 (フー・ファイターズ その② Fū Faitāzu Sono 2), originally A Trade Covered in Wounds (傷だらけの取引 Kizu Darake no Torihiki) in the WSJ release, is the thirty-second chapter of Stone Ocean and the six hundred twenty-sixth chapter of the JoJo's Bizarre Adventure manga.
Water sprays all over the floor of the barn as Foo Fighters and Jolyne stare at each other intently; Jolyne asks F.F. if it knows the identity of Whitesnake, to which the latter replies that it doesn't know much. Jolyne attacks with Stone Free, and she tries to sneak a string past the Stand as the attack is blocked. F.F., however, notices it immediately and assimilates with the puddle on the floor.
F.F. begins to merge into Jolyne, mocking her, believing that it created the perfect environment for itself. However, this was all part of Jolyne's plan, and the string was just a distraction. She had used another string to start the engine of the tractor where the discs are stored. The running water blocked the noise of the engine, and while F.F. was preoccupied with Jolyne, the tractor had driven out into the field where Ermes could catch up to it. F.F. runs for the tractor, leaving Jolyne behind. As it runs on the dry fields, F.F. loses its body parts. By the time it reaches the tractor, most of its body is gone due to lack of water.
Ermes grabs a pile of dirt to finish it off, but Jolyne stops her. She pours water on the Stand in an attempt to rescue it, believing F.F. only protected the discs as a way of protecting its own identity. Jolyne then makes a deal with F.F; that it would be allowed to live as long as it allied with Jolyne against Whitesnake. Despite not fully understanding her feelings, F.F. agrees to join the team.
