Flash Flood Warning (3) (集中豪雨警報発令 その③ Shūchū Gōu Keihō Hatsurei Sono 3), originally Searching for the Lost (探し物 Sagashi Butsu) in the WSJ release, is the six hundred forty-fourth chapter of the JoJo's Bizarre Adventure manga. It is also the fiftieth chapter of Stone Ocean.
Jolyne's string net keeps the raining frogs out, but their toxic fluids continue to soak through. Whitesnake enters the courtyard in search of Jotaro's Stand Disc. With Whitesnake's long range, Pucci is able to safely hide within the prison. Whitesnake stumbles upon Jolyne's corpse covered in frogs, and finds the disc nearby. However, Jolyne was simply waiting for Whitesnake to find the disc, and uses a string to grab it.
She reveals that she used strings to catch the frogs and cover herself with them; As long as they don't explode, their deadly poison can't come in contact with Jolyne. As Whitesnake goes to kill her, it is revealed that the SPW messenger was actually a pigeon, named Savage Garden, which Jolyne attached the disc to with a string.
Whitesnake rushes toward the gate where a gun is lying. He grabs it and attempts to shoot down the pigeon, but the guard had used all the bullets. Whietsnake promptly makrd his exit as he heas guard approaching, and Jolyne attaches a string to the Stand in order to uncover its user. Whitesnake successfully returns to Pucci; not actually requiring the Stand Disc, his plan remains intact.
