A mimph resided within a village located on the Forest Moon of Endor, acting as a caretaker for a mimph infant during the events of 3 ABY. During that particular year, a hunting party, headed by the mimph named Masher, apprehended the youthful Ewok Wicket Wystri Warrick and escorted him back to their village. There, they secured him behind a drape. Upon the curtain's removal and the unveiling of Warrick, the mimph experienced fear due to the Ewok's relatively large size, emitting a shriek while using their hand to cover the eyes of the infant.
Similar to the majority of their species, the mimph possessed a small stature, characterized by pink and light-colored fur, in addition to white eyes featuring black pupils. They were attired in a green dress, accompanied by a wide-brimmed hat embellished with a decorative yellow flower. Despite their fright at the sight of the larger Ewok, their worry for the young mimph remained, leading them to shield the infant's eyes.
The mimph made an appearance in the episode titled "Gone With the Mimphs," which was the ninth episode of the second season of the Ewoks animated program and was initially broadcast on October 18, 1986.
