Broggy

Broggy is a monstrous dog-like creature coming from Mario & Luigi: Bowser's Inside Story whom serves Broque as his guard dog. It seems to be made from a yellow ? 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 the Koopa Equipment shop.

Broggy is fought once in the game. He fights Bowser thinking he's an intruder. Bowser has to attack Broggy with his fire breath and set 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. One of Broggy's attacks is tackling into Bowser. Broggy also appears to help Bowser as a special attack, called Broggy Bonker that is unlocked by saving all fifteen Blittens.

If the Mario Bros. talk to Broggy, he will growl in a manner much more menacing than he does to Bowser.
