Minions vs. Minions
From the Super Mario Wiki
Captain Goomba and Captain Shy Guy attempt to enter Beanbean Castle Town, which had recently been attacked by Fawful, when they are stopped by a Lakitu who informs the two captains that they need more allies. Just as he is about to offer to look for more minions, though, he is captured by a brainwashed Larry and is taken to his hideout. They battle Lakipeas and Paratroopeas in this level. Afterwards, Captain Goomba, who cannot work around the fact that the Koopalings are brainwashed, decides to unbrainwash and recruit them one by one.
