Vacuum Block
The Vacuum Block is a key block item from Mario & Luigi: Bowser's Inside Story and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. It is a green (yellow in the remake) block that allows Bowser to use the Vacuum command in battle.
When Bowser meets Broque Monsieur, the latter is stranded on a small island off the coast of Plack Beach. Broque Monsieur implores Bowser to rescue him, but Bowser is unmoved. Just as Bowser is about to leave, however, Broque Monsieur offers the Vacuum Block as incentive for his rescue. Seeing this, Bowser agrees to assist Broque Monsieur. Picking up a small rope that is tied to the island, Bowser drags Broque Monsieur to shore with the help of Mario and Luigi.
The Vacuum Block allows Bowser to use the Vacuum Mushroom's power offensively. Bowser can use it to uncover the hidden Blitties during battle and to steal various helpful items or other objects like lollipops from Chuboombas that recover HP, teeth from Crawfuls and body segments from Toothies that boost his defense, and meat seen in the second Midbus battle to boost his attack power. Additionally, it can be used to inhale some entire monsters like Coalbits, the Stone Blooper and Snawfuls, forcing the Mario Bros. to fight them in Bowser's body. This last function features heavily in the final battle with Dark Bowser and the Dark Star Core; after releasing the Dark Fawful Bug from Dark Bowser's body, Bowser can inhale it so Mario and Luigi can battle it inside his body and defeat it so Bowser can finish off Dark Bowser.
