Broggy Bonker is a Special Attack that can be only used by Bowser in Mario & Luigi: Bowser's Inside Story. The attack uses twenty SP to be able to be used. This attack is unlocked once all 15 Blitties are collected and returned to Broque Monsieur. Depending on how well the Action Command for the attack is performed, the attack's damage will either be better or worse:
- OK — Broggy will charge into the enemy once from the front.
- Good — Broggy will charge into the enemy twice, one from the front, then from the back.
- Great — Broggy will charge into the enemy once from the front, then slam down on it from above.
- Excellent — Broggy will charge at the enemy, jump up for a slam, doubling damage, continue on, turn around and charge into the enemy, trailed by the 15 Blittys, who also cause some damage on the enemy.
