The Invincishroom is an item in Mario and Luigi: Superstar Saga. Made from Stars from the Mushroom Kingdom, its function is unknown. They come from Little Fungitown.


In Mario and Luigi: Superstar Saga, Mario wins an Invincishroom in an arcade game. Mario eats it, but is not used to the food around Little Fungitown and gets Bean Fever. Luigi must then get Crabby Grass to cure him.


  • Although being made from stars, the Invincishroom looks exactly like a Poison Mushroom.
