Rocky is the Eridian alien companion in Andy Weir's Project Hail Mary, first published in 2021, where he befriends astronaut Ryland Grace aboard the Hail Mary spacecraft. Because Eridians communicate through sound rather than human speech, Rocky's musical voice became one of the book's most distinctive and beloved details. Readers and fan creators have since shared short audio moments of his singing in edits, memes and reaction videos, keeping the character alive between the novel and its screen adaptation and giving fans a simple way to signal warmth, curiosity and unlikely friendship.
