Template:Organization-infobox The Aku Iwagumi (悪岩組, Evil Rock Gang) is a gang of Thwomps that commands the rocks from Chocolate Island, it appears in chapter 6 Super Mario-kun volume 3.

While in sight of Wendy's Castle, Mario, Luigi and Yoshi takes a break. The latter, inspired by the autumn, decides to sculpt a statue from a rock, only to realize it's the Aku Iwagumi's leader, an old and blunt Thwomp. Thwomp, who just got a day off from Bowser, arrives and accuses Mario of hurting his old boss, just then, Mario notices Yoshi left his sculpting tools in his hands.

Thwomp, helping his old boss, commands the nearby rocks to attack them. Mario's party has the upper hand, but loses Mario's cape in the fight, which falls in a Warp Pipe. After Thwomp squashes them, him and his boss calls the Thwimps to finish them. The cape, thanks to some bubbled Mushrooms, re-emerges, so Mario uses it to sack the Thwimps in the cape and smash it on Thwomp, breaking his spikes, and his boss, breaking him into little old Thwomps. The spliced old leader's parts keep fighting with themselves for the title of gang leader. Laughing, Mario comments on how now the group should be called 「弱岩組」 (Weak Rock Gang).
