Meanwhile the Millenium Ring had led everyone into a maze. Tea guessed that Pegasus had ordered the creation of the maze to confuse duelists. The Millenium Ring kept of glowing so the gang followed it. They then found themselves out of the maze, infront of the Paradox Brothers. The two brothers told them that Yugi would have to beat them to move on. Yugi didn't seem to worried until they told him that they were elimnators for Pegasus. Yugi accepted their challenge, but they told him that one duellist would lose so they would have to duel as a team. The Paradox Brothers then told Yugi that if they won they would be faced with another challenge. As the four duellists began to duel, Seto Kaiba is heading towards Pegasus's castle to save his brother.
Para explained that everyone would start off with 2000 life points, but if one person lost all their life points, their team would lose the duel. He then told them that they would alternate turns. Dox started the duel by activating Labyrinth Wall, to make the entire field a maze. The Paradox Brothers than told Yugi and Joey the rules to a maze duel. As Yugi and Joey absorbed the information, the Paradox Brothers told them also to worry on their second challenge if they won. They must choose between two doors and if they pick the right door they will leave the cave, but if they pick the wrong door they will be stuck in the maze. Para then told them that for they would allow each duellist to ask a question. One of them would tell the truth while the other would lie.
Joey remembered a puzlle that was similar to this one. "A boy arrives at a junction with two roads leading from it, one to Truthsville and one to Liarsburg. A man is standing a the junction but the boy does not know which town he is from. In order to be taken to Truthsville, the boy asks the villager to atke him to their own village, seeing as both villagers would have taken him to Truthsville (as the lia could not take him to Liarsburg without telling the truth)."
Certain that he could find the liar, Joey asked the two brothers to point to the door on the right. Both brothers pointed to the door Dox was guarding, making Dox the truthful brother. Yugi was not sure so he told Joey that both brothers said that one of them would tell the truth while the other will lie. This meant that one of the brothers would have admitted that they were the liar and that wasn't possible. Yugi then told Joey to forget about the puzzle and focus on the duel
Yugi then summoned Beaver Warrior and moved him four spaces through the maze. Para activated Polymerization and fused Shadow Ghoul with the Labyrinth Wall to create Wall Shadow. Wall Shadow could travel through wall so it could go any where in the maze in one turn. Wall Shadow then destroyed Beaver Warrior(Yugi's LP:1600). Joey summoned Axe Raider and laid one card face down. Dox summoned Labyrinth Tank and moved it seven spaces into the maze. He also played Jirai Gumo face down, so when a monster stepped on it, it would attack. Yugi summoned Celtic Guardian and moved it four spaces through the maze. Para ordered his Wall Shadow to attack, but Joey activated Kunai With Chain. Then Yugi destroyed Wall Shadow(Para's LP:1700). Yugi then warned Joey to stay on his guard. Meanwhile Croquet informed Pegasus that Seto had been spotted on the island, htough Pegasus already knows. Meanwhile Mokuba was wondering where his brother was.
