Reclaim the Red Goblet!
From the Super Mario Wiki
Captain Goomba and Captain Shy Guy run into Cork and Cask, who explain that their Red Goblet has been stolen. The two captains agree to go look for it in exchange for information on Iggy, battling Koopa Paratroopas and Parabeetles until they beat the Koopa Paratroopa with the goblet. With the goblet returned, Cork and Cask point out where Iggy has gone while providing a map to Mother Chuckalola, and the Goomba Squad heads there.
