Antlered eopies, which are also referred to as horned eopies, represented a species of four-legged mammallians that inhabited the planet known as At Achrann. These creatures were a unique type of eopies that were also found living on the worlds of Tatooine and Saleucami.
The Troik named Hayna recounted to the group of four younglings from Skeleton Crew that a Hattan patrol had absconded with their horned eopies. SM-33 and Jod Na Nawood engaged in negotiations with the Hattan, ultimately providing them with some of Wim's dataries as payment in return for the complete collection of animals. Subsequently, Nawood and SM-33 facilitated the return of the animals to the Troiks.
The debut of horned eopies occurred in the Star Wars: Skeleton Crew episode titled "Can't Say I Remember No At Attin," which was the fourth episode of the series. The initial appearance of eopies was in Star Wars: Episode I The Phantom Menace, and they later reappeared in Obi Wan Kenobi.
