Vacuum Shroom

"Such a special treat called the Vacuum Shroom! I, Fawful, invented it to make you inhale everything you see!"

- Fawful

The Vacuum Shroom is an item in Mario & Luigi: Bowser's Inside Story. Bowser, after his last defeat, finds a random shop-like area managed by Fawful in the middle of the forest. Here, Fawful gives the Vacuum Shroom to Bowser, calling it a "Lucky Shroom" and claims that it will give him the power to beat Mario. Bowser then uses the Vacuum Shroom, which gives him the ability to inhale everything like a powerful vacuum (similar to Bowletta in Mario & Luigi: Superstar Saga or Kirby from the Kirby series). It was presumed destroyed after Fawful is defeated: however, Mario and Luigi: Dream Team reveals that Bowser is still capable of inhaling in that game, implying that the Vacuum shroom did not perish with its creator. Using the mushroom makes Bowser feel tired and objects he inhales somehow shrink drastically. The Vacuum Shroom is similar to the Invincishroom of Mario & Luigi: Superstar Saga; both are mushrooms which are touted to have positive effects which do not actually end up being bestowed when consumed by the player.
