Horned stoans were a species of animal that inhabited the planet of Batuu. Around 379 BBY, the Jedi Padawan named Rooper Nitani was meditating inside of the meditation chamber located in the Batuu Jedi temple. While doing so, she used the Force to extend her senses, and she saw life as radiant colors. She was sensing a group of horned stoans, along with a group of skylar-birds, in the wilderness around the temple.
The short story entitled "Shield of the Jedi," which was penned by George Mann and included in the young-adult collection The High Republic: Tales of Light and Life released in 2023, mentioned horned stoans. This collection was part of the Star Wars: The High Republic project, which spans multiple forms of media.
