Not Bug-Eaten highly resembles Bug-Eaten. However, it appears to have smaller fangs, and a darker brown fur. Also, unlike Bug-Eaten, neither of its ears seem chewed off.
Both rats also sport a strange, ogival-shaped, protuberance on their foreheads. However, the horns on Not Bug Eaten are notably shorter than its counterparts. In the TV anime, this distinction is omitted with the protuberance looking virtually identical for both rats.
The series is known for alternating colors between media, the information presented below may or may not be canon.
(Brown fur, tan skin, indigo nose, flesh pink protuberance)
(Dark Brown fur, gray skin, black nose, metallic gray protuberance)
Not much can be determined about Not Bug-Eaten's personality. However, like Bug-Eaten, Not Bug-Eaten also displays hunger towards humans, fueled by confidence after having acquired a Stand.
While Akira Otoishi had Keicho Nijimura's Arrow in his possession, he tested its powers by using it on two rats living in the farmlands surrounding Morioh. The arrow pierced the rats, granting them both the Stand Ratt. Thanks to their power, the pair of rats took dominance among the local rat population, melding their rival rodents together.
Believing that only one rat exists, Jotaro and Josuke go hunting for it for damage control after Jotaro questions the defeated Otoishi.
Diamond is Unbreakable
Not Bug-Eaten and Bug-Eaten find and attack a couple of old farmers, melding their flesh together and stuffing them in the fridge for preservation. They also make a nest in a drainage pipe.
When Josuke investigates a couple's house, he is horrified to find Not Bug-Eaten eating melted flesh of the couple in the fridge beside it. Josuke manages to use Crazy Diamond to fire a steel marble at its side, but it doesn't die. Wounded and surprised, the rat runs and hides behind a chair, revealing its Stand. Josuke quickly manages to determine by the Stand's shape that it's a turret-like Stand that shoots, and reacts quickly by shooting another steel marble at the rat; the Stand shoots a dart back, which Josuke barely manages to block in time with a frying pan. Not Bug-Eaten then emerges from its hiding spot, but faints as it bled to death.
Josuke thinks that he's taken care of the situation when Jotaro informs him that there are two rat Stand users, and that Josuke only killed one.

The two rats' appearances in the anime are almost identical aside from their right ears. However their appearances in chase and I Want You, as well as their respective model sheets more easily distinguish them, akin to how they were drawn in the manga.
