In Daring Done?, Somnambula is the namesake of a village in Southern Equestria and a pony of legend as told by one of its villagers. In the story, the village is menaced by an evil sphinx that claims most of their crops for herself. Somnambula uses what little she has to offer, such as her pearl necklace, to provide food to the poor villagers and give them hope. Inspired by Somnambula's compassion, the pharaoh's son, Prince Hisan, stands up to the sphinx, but the beast captures him and challenges the ponies with a riddle in exchange for his release.

Somnambula accepts the sphinx's challenge and correctly answers the riddle, enraging the sphinx. Fearing the monster would go back on her promise, Somnambula asks for one more challenge and tells the sphinx to leave the kingdom forever if she completes it. The sphinx thus makes Somnambula walk toward Hisan across a narrow bridge blindfolded and without flying. Guided by Hisan's voice, Somnambula succeeds with a leap of faith, and the sphinx furiously flies away. In gratitude for saving him, Hisan replaces Somnambula's pearls with a string of glowpaz, with a statue erected and the village named in her honor.

In present day, Somnambula's statue is accidentally destroyed during one of Daring Do's adventures, and A. K. Yearling uses her funds to restore it.
