Appearances
Mario & Luigi: Bowser's Inside Story
His first appearance is in Plack Beach, when he was stuck on an island and called for help. Bowser, passing by, helped him and in return Broque gave him the Vacuum Block. Later in the story, Broques dog Broggy stopped listening to him, so Bowser had to fight Broggy. Afterwards, in Dimble Wood, you see Broque in his shop, and he would only serve Bowser, who had a fate with Broque. He also asked Bowser to find and capture fifteen Blitties, and as a reward, Broque would let Bowser take Broggy for a "walk," and then he is able to use the Broggy Bonker move. He often referred to Bowser as the "Monsieur Turtle Bits."
He is also a block collector, and since Mario hits blocks instead of collecting he doesn't allow Mario or Luigi to shop at his store.
Despite being just a Shopkeeper, he is crucial in the game, as the Vacuum Attack is needed to destroy the final boss.
