Jotaro brings Josuke along with him to track down a rat that had been turned into a Stand user by Otoishi, teaching him how to fire ball bearings. During their search, the pair discover several rat corpses that had been melted from the inside and merged together into a gelatinous flesh cube. Investigating an abandoned house, Josuke comes up against the rat, who had merged the home's owners together. Withstanding Josuke's initial attack, the rat attacks with its Stand, Ratt, before it succumbs to its injuries and dies. However, Jotaro then reveals that he had encountered a second rat with the same ability, which escapes out of the house. While pursuing the second rat, which Jotaro names Bug-Eaten, Josuke falls into a trap and gets hit by one of Ratt's needles, though is saved thanks to Jotaro's time stopping ability. Jotaro then uses himself as bait to lure out Bug-Eaten, tasking Josuke with pinpointing its location and shooting it. Despite the pressure put on him by Jotaro's increasing injuries, Josuke manages to focus and lure Bug-Eaten out into the open, allowing him to successfully make the kill shot.
