The Starshade Bros. (Sergeant Starshade and General Starshade) are two Cosmic Toads in Mario & Luigi: Superstar Saga and it's remake that teach Mario and Luigi the "Spin Jump" and "High Jump" moves. One is red, and the other is green. They both wear sunglasses and large teeth and are found in the Beanbean Borderlands. They, along with the Border Bros., form the border patrol for the Beanbean Kingdom and Mushroom Kingdom.
After the Mario Bros. defeat Tolstar while Bowser is stuck in a cannon, Bowser's griping annoys Sergeant Starshade, who appears and sets off the cannon, knocking Bowser into Tolstar and causing him to lose his memory.
