Grymi was a Ferengi man. He was a musician, the windsqueezer player of Success.
Success has been scheduled to perform at the Isle of Grub Festival, which was billed as "Five Days of Music, Oo-mox, and Merchandising," but canceled their appearance when Grymi and his wife, Pino, instead decided to spend the day tied up in a tube grub harvesting sack, and the rest of the group left for Risa. The absence of Success caused a riot that injured over a hundred thousand. Soon after, Success released the album In Memory of the Fallen, a Tribute to the Tragedy at Grub, including the song "Grymi Says He's Sorry". The album sold a hundred million copies.
