Elite Trio

The Elite Trio is a group of three enemies that appear in Mario & Luigi: Dream Team, but all three members first appeared in Mario & Luigi: Bowser's Inside Story. It is made up of Private Goomp, Corporal Paraplonk and Sergeant Guy. They are fought in Dreamy Driftwood Shore after being found with Kamek, who is disguised as Princess Peach.

Battle
All three troops must be defeated at once, as they can revive each other with only 1 HP,then heal even more HP because of Paraplonk, who has an inexhaustible amount of Mushrooms, in a similar way as the Bowser Memory ML from Mario and Luigi: Bowser's Inside Story.

Sergeant Guy's attacks are: turning Private Goomp's Goomba horde into copies of the Sergeant, which then attacks Mario from all four sides. Hitting the authentic Guy will end the attack. He also attacks launching Banzai Bills from his Sergeant Guy Cannon. This attack can only be avoided by attacking the cannon as soon as the bullet is inserted, causing massive damage to all enemies.

Corporal Paraplonk's attack is hitting blocks near Mario and trying to run him over. If Mario stomps on him successfully, he will damage Goomp, and the first row of the Sub-Goomba in the background.

Private Goomp's attack to make the sub-Goomba horde pile up to a rectangular shape, then sends it to smash into Mario. Mario must stomp on them, to make the pile go back to Goomp, who then stops them, then sends them back again to Mario. If Mario does not stomp on them, they will go behind him, then individually charges into him.

The last attack they have consists of Sergeant Guy of getting a huge Bob-Omb with the help of Paraplonk, then chases Mario vertically. Goomp will realise this only too late, and will end up behind his horde. He will urge them to go forward, in order to get to safety. Mario must stomp on him whenever he finds an opening to make him slow; the bomb will go off, dealing massive damage to Guy, the Sub-Goombas who failed to escape, and possibly Goomp, depending if he managed to escape.

Aftermath
After the trio's defeat, Kamek demotes them to to janitors for losing, then teleports them out. Mario and Luigi briefly encounter the Elite Trio again when they are going after Bowser after defeating Antasma for the final time. This time, the three minions decide to roll giant Bob-ombs down the spiraling ramp to prevent the Bros. from getting up to Bowser. During the credits of the game, Private Goomp and Sergeant Guy end up rocking the Koopa Clown Car so much trying to collect coins that it falls into the ocean, prompting Paraplonk (with assistance from Kamek) to rescue them and Bowser.

Battle Ring
The Elite Trio can also be battled in the Battle Ring as the Class 6 boss battle, in the form of Elite Trio X, where they have higher stats than when fought previously. Unlike most X bosses, the Elite Trio does not have an alternate color scheme, but the background is now yellow instead of pink.
