During their journey in Paper Mario: The Thousand-Year Door, players will come up against many difficult foes. However, none are quite as difficult as the Iron Clefts found in the Glitz Pit. After Mario finds the way to Glitzville, he'll join the popular fighting arena and battle his way to the top.

Starting in the minor leagues, players should easily make their way up to their qualifying match at Rank 11. But when Mario goes up against the Ranked 10 Iron Adonis Twins, players will find themselves in an impossibly difficult scenario: their opponents' iron hides are too tough to pierce.

Though most of the combatants in Paper Mario: The Thousand-Year Door talk a big game in the Glitz Pit, few can back up their claims as strongly as the Iron Adonis Twins. With an official defense of ???, it's surprising that this dynamic duo sits at the bottom of the major league rankings.

With the help of one of the game's partner abilities, players can get all the information they can about the two Iron Clefts. Goombella's Tattle will reveal that no attack will work against their tough exterior, and suggests that, if true, the only way to beat one is to whack it with the other. Unfortunately, neither Mario nor any of his partners in the ring have the ability to do anything of the sort.

The Iron Adonis Twins are impossible to beat the first time around. Though it might seem counter-intuitive to some, the only way to progress in the game is to lose or flee from the fight.

The egg hatches into the party's latest addition, a young Yoshi with a fiery passion for battle. Though his stats and abilities are always the same, players can pick Yoshi's color by resetting and waiting a different amount of time before hatching.

When it's Yoshi's turn to attack, players can use his Gulp to inhale one of the Iron Clefts and spit it at the other. Ideally, players should rest before entering the fight or at least have enough FP on hand, as Gulp costs a whopping 4 FP per use.
