Starshade Bros.

The Starshade Bros. are the two people in Mario & Luigi: Superstar Saga that teach Mario and Luigi the very important "Spin Jump" and "High Jump" Moves, which are necessary later on in the game. They are Toads, one red and one green, with sunglasses and large teeth. They, along with the Border Bros., are the border patrol for the Beanbean Kingdom and Mushroom Kingdom.

Their heads resemble Cosmic Toads, which they might be. They may even be a "Beanified" Toad!
