Double Trouble Koopaling Caper
From the Super Mario Wiki
Captain Goomba, Captain Shy Guy, Captain Boo, and Captain Koopa Troopa manage to find Lemmy and Ludwig, who both try to block their way. The fight immediately ensues, and the Goomba Squad battles Mechakoopas, Dry Bones, and Lemmy and Ludwig themselves. When unbrainwashed, Ludwig becomes surprised that Captain Goomba (whom he had encountered previously at Hoohoo Mountain) had led all of the other minions this far, and he and Lemmy promptly join the Goomba Squad.
