Broggy is a monstrous, cuboid Brock dog in the game Mario & Luigi: Bowser's Inside Story whom serves Broque as his guard "dog". He seems to be made from a yellow Question Block, with four legs and large ears on each side of its body. On its rear side, Broggy has a band-aid. Broggy protects Broque's Block store against intruders and runs his own store: the Koopa Equipment shop.
 Mario & Luigi: Bowser's Inside Story
Broggy's first appearance is on Plack Beach, when Broque is yelling for his Broggy. He and Bowser then find him on a cliff, hiding from the two. He then proceeds to smash into Broque, knocking him onto his side. Bowser criticizes the fact that Broggy is his pet and he replies with "Oui, but he is not his usual self today". Bowser prepares to land a few punches on Broggy, but Broque gives a loud cry of "NON!" and tells him to use his fire abilities on him or Broggy will win. Bowser does this without too many problems and reigns victorious.
Broggy only has two attacks. One of them is to charge straight at Bowser, which must be countered by punching. Doing so will send Broggy flying into Broque, throwing him offscreen. Broque will then will crawl back to his original position. The other attack is to jump onto Bowser, which must be countered by ducking. If Bowser successfully dodges, Broggy goes offscreen. However, the attack is not over then. Broggy will be coming back for more, making thumping noises and making the screen shake. Broggy will jump onto Bowser from behind, which is dodged by ducking again. If that is dodged, Broggy will once again smash into Broque, sending him offscreen. Before both of these attacks Broggy's eyes will flash red rapidly. Bowser has to attack Broggy with his Fire Breath and sets him on fire. While Broggy is burned, he turns to the other side so his band-aid is vulnerable. Bowser has to attack Broggy's band-aid until he is defeated. After a couple of turns, the burn disappears and he continues fighting.
Broggy also has his own store, stately known as Broggy's Shop, where he sells gear. Broggy also appears to help Bowser as a special attack called Broggy Bonker that is unlocked by saving all fifteen Blitties. However, if the player collects all fifteen Blitties and gets Broggy Bonker, Broggy's Shop will no longer be open for business, due to the absence of Broggy. However, when this happens, Broque's shop will be able to sell both gear and items.
If the Mario Bros. talk to Broggy, he will growl in a manner much more menacing than he does to Bowser. This could indicate that not only is Broque Monsieur himself reluctant towards them, but Broggy is as well.
 Mario & Luigi: Dream Team
Broggy reappears in Mario & Luigi: Dream Team, where Dr. Snoozemore uses him to send a letter to Princess Peach and Mario, which is an invitation to Pi'illo Island. It is revealed that he has a communication screen behind his bandage, that Snoozemore uses to communicate to Mario.
