The Elite Trio (Private Goomp, Sergeant Guy, Corporal Paraplonk) will challenge you multiple times, but their final encounter is the most formidable. They fight as a group, making crowd control and target prioritization crucial.

- Private Goomp: Focuses on physical attacks and summoning Goombas. Take him out first to reduce enemy numbers.
- Sergeant Guy: Uses ranged attacks with his spear and can heal himself or his allies. Prioritize him after Goomp.
- Corporal Paraplonk: Flies and drops bombs, often targeting both Bros. He has high defense but can be knocked down with jump attacks.
Strategy: Use Bros. Attacks that hit multiple targets, like 'Luiginary Ball' or 'Star Rocket', to soften them all up. Focus fire on Private Goomp first to eliminate his summons. Then, target Sergeant Guy to stop his healing. Finally, deal with Corporal Paraplonk. Be mindful of their combined attacks, which can be devastating. Use 1-Up Mushrooms if a brother falls. This fight is a test of attrition and target management. Reward: Significant experience and access to the final areas of Neo Bowser Castle.
