Chapter 554

"Green Day" and "Oasis" (1), originally Leave It to Mista! in the WSJ release, is the five hundred fifty-fourth chapter of the JoJo's Bizarre Adventure manga. It is also the one hundred fifteenth chapter of Vento Aureo.

Summary
Narancia is being consumed by the mold, and doesn't manage to crawl to the shores, so Mista shoots the engines of the boat, causing a small explosion which propels Narancia up toward Mista and ejects Buccellati out of Coco Jumbo. As Narancia is transferred into the turtle so that Giorno can treat him, Buccellati and Mista plan to go up the stairs and hijack a car to get out of the attack's range.

Watching everything from afar, Cioccolata is amazed that anyone could escape his Green Day, and asks Secco if he's recorded everything. Secco nods and is given sweets as a reward. Cioccolata then sends Secco fighting Mista and Buccellati.
