Captain Goomba and his squad are faring surprisingly very well for themselves when they encounter two Hammer Bros., along with Mallet and Sledge. The latter four characters bond over their love of hammers, but Captain Goomba declares they must come with his squad, and the reluctant Hammer Bros. battle to see what happens, with Captain Goomba's squad coming out victorious in the end. The Hammer Bros. part with Mallet and Sledge and join the growing squad of minions.
