SO Chapter 50

Torrential Downpour Warning, Part 3 (集中豪雨警報発令 その③), originally in the WSJ release, is the fiftieth chapter of Stone Ocean and the six hundred forty-fourth chapter of the JoJo's Bizarre Adventure manga.

Summary
Jolyne's string net keeps the raining frogs out, but their toxic fluids continue to soak through. Later, after the rain of frogs ends, 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 Speedwagon Foundation 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. Whitesnake promptly makes his exit as he hears guards approaching, and Jolyne attaches a string to the Stand in order to uncover its user. However, Whitesnake notices the string and cuts it before successfully returning to Pucci. As Pucci has no need for the Stand disc, his plan remains intact. Moreover, Jotaro still requires his memory disc in order to be fully revived.

Trivia

 * From the tankōbon edition onward, an additional spread of Savage Garden in the sky is added, along with text clarifying that Jotaro still requires his memory DISC.
