Shin Uchiha has several of these creatures working in his service. They have an askew mouth, a nose, four small limbs, and what appears to be a tail. Their single eye features a fully matured Sharingan.
The creatures are very stealthy, able to spy at the gate of Konohagakure without being detected. Shin Uchiha and his sons are able to use the creatures as a medium in various ways, such as seeing what the creatures do for reconnaissance or communicating through the creatures. The creatures' Sharingan can be used to perform 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.
