Mushikui is a stand-using brown rat from Part IV: Diamond is Unbreakable. While without evil intent, the rat bear natural instincts of eating and go after even humans as a food source.

Diamond is Unbreakable
While Akira Otoishi had Keicho Nijimura's Arrow in his possession, he tests out its powers by using it on two rats. The arrow pierces the rats, granting them both the stand, Ratt.

Believing that only one rat exists, Jotaro Kujo and Josuke Higashikata go hunting for it for damage control after Jotaro questions the defeated Akira. In the process, the two rats had managed to meld together the bodies of other rats into cubes of flesh.

The two protagonists follow a drain pipe to an empty house and discover a rat in the kitchen in the process of testing it's stand ability on humans. Josuke quickly disposes of it, but is surprised by the presence of the second rat, who Jotaro names Mushikui. After moving their battle outside, a deadlock commences with both sides refusing to move from their cover. Mushiki is eventually shot and killed when Josuke tricks the rat from moving from its cover.

Trivia

 * The hole in its ear is likely a wound from the Arrow, making both rats stand users.
 * "Mushikui" is a name given by Jotaro, referring to the hole in its ear.
