Sharingan Spying Creature

This mysterious creature belonged to Shin Uchiha.

Appearance
It had four small limbs and what appeared to be a tail, an askew mouth and a nose. Its single eye featured a fully matured Sharingan.

Abilities
The creature was very stealthy, able to spy at the gate of Konohagakure without being detected. Its vision was linked to Shin Uchiha and his son's, enabling them to notice the movements of their targets. The creature could also act as a verbal communication medium, seen as Shin received orders from his father through it. With its sharingan, the creature could use a type of space–time ninjutsu, although it is unknown if it possessed this ability itself or if it acted once again as a medium. The creature can also take the form of Shin's Mangekyō Sharingan.

Naruto Gaiden: The Seventh Hokage and the Scarlet Spring
One of the creatures noticed Sarada Uchiha departing from Konohagakure. Upon Shin see this via their linked vision, he orderd one of his sons to capture her. Seeing as the clone couldn't capture her with the interference from the Seventh Hokage, the creature suggested that they retreat, which the creature did by using space–time ninjutsu.

Later, when its master was ready to begin another attack, one of the creatures at the Ridge Tower teleported Shin and one of his sons to its location. After the father and son were defeated, the creature teleported them and Sakura Uchiha back to their hideout. When the Shin clones betrayed their father, Shin attempted to kidnap Sarada and Chōchō for hostage purposes, ordering one of the creatures to take them. However, Sarada caught sight and punched the creature in the eye, killing it.
