"Quiz Quagmire: Part 2", known as "A Difficult Question!? Attack Duel Quiz!!" in the Japanese version, is the twentieth episode of the Yu-Gi-Oh! ARC-V anime. It first aired in Japan on August 24, 2014 and in Australia on November 15, 2015. It became available with official subtitles via Crunchyroll on November 22, 2016.
The "Quiz Duel" between Pierre L'Supérieure and Yuya enters an extra stage. Both of them travel on separate tracks in this Quiz field facing different Action Cards. In this stage, where answering a question wrongly will incur a punishment, Yuya feels exhausted as he continuously answers wrongly. However...
The first "Quiz" question Yuya finds depicts two "Raigeki Break" cards, one with two fingers held up on the hand, another with only a single finger, and Yuya must say which is the correct one. Yuya is given five seconds to answer, but he fails to do so, so he takes 100 damage (The correct answer being the one with one finger held up.) (Yuya 800 → 700) The second "Quiz" question Yuya finds is "How many people are being blown away in "Heavy Storm". He answers "two," but the answer is three, so he takes 100 damage. (Yuya 700 → 600) Yuya is shown to get all three remaining questions wrong. (Yuya 600 → 500 → 400 → 300)
One of Pierre's questions is "How many teeth does "Pot of Greed" have?" He answers correctly (20 teeth), so he gains 100 Life Points. (Pierre 5800 → 5900) Pierre answers all four remaining questions correctly. (Pierre 5900 → 6000 → 6100 → 6200 → 6300) The effect of "Extra Stage" ends and they return to the Duel Field.
Pierre then activates the effect of "Quiz Sphinx". Yuya is asked which monster on the field has the highest Level. If he answers correctly, that monster is destroyed and the controller takes damage equal to its ATK. If he answers incorrectly, the Battle Phase will be ended. As answering correctly (which would be the Level 7 "Odd-Eyes with 2500 ATK) would cause Yuya to lose, he answers "Quiz Monkey," (Level 1) and the Battle Phase ends. Since he answered "Quiz Monkey's" question incorrectly, Eita destroys "Odd-Eyes." ("Quiz Monkey": 1500/1000 → 2500/2000) Yuya activates the effect of "Performapal Lizardraw"; since a monster he controlled was destroyed, he can draw a card for each "Peformapal" monster he controls, so he draws 2 cards. Yuya Sets 3 cards.
Turn 5: Pierre
Pierre draws. Pierre attacks "Whip Snake" with "Quiz Monkey." Yuya activates the Trap Card "Last Minute Cancel", switching all monsters he controls into Defense Position and this turn, if any "Performapal" monsters he controls are destroyed, they are returned to his hand instead. "Quiz Monkey's" attack continues and "Whip Snake" is destroyed and returns to Yuya's hand. "Quiz Sphinx" attacks and destroys "Lizardraw," which is also returned to Yuya's hand. Pierre activates the Quick-Play Spell Card "Double It!!", doubling the ATK of a "Quiz" monster that destroyed a Defense Position monster by battle and allow it to attack again. ("Quiz Sphinx": 1000 → 2000 ATK) "Quiz Sphinx" attacks Yuya directly, but Yuya finds and activates the Action Trap "Quiz Action - Math for 5000". He must prove Fermat's Last Theorem (in the dub, Yuya must identify the first 100 digits in the number pi).
If he does, he will gain 5000 Life Points, but if he doesn't, he'll take 5000 damage. Yuya deliberately answers incorrectly (or rather, deliberately chose the card in the first place with the knowledge that he couldn't answer), so he takes 5000 damage. Yuya activates the Trap Card "Performapal Reborn Force". If he would take effect damage during the turn a "Performapal" monster was destroyed, he can inflict that damage to his opponent instead. (Pierre 6300 → 1300) The second effect of "Reborn Force" ends the Battle Phase since it was activated during the Battle Phase. Pierre Sets 2 cards. The effect of "Double It!!" ends and the ATK of "Quiz Sphinx" returns to normal. ("Quiz Sphinx": 2000 → 1000 ATK)
Turn 6: Yuya
Yuya draws. Yuya Pendulum Summons "Performapal Hip Hippo" (800/800), "Performapal Whip Snake," and "Performapal Lizardraw," from his hand and "Odd-Eyes Pendulum Dragon" from his Extra Deck. Pierre activates the Trap Card "Final Question", forcing Yuya to guess how many monsters will be on the field at the start of the Battle Phase. If he guess correctly, all of Pierre's monsters will be destroyed, but if he guesses incorrectly, all of Yuya's monsters will be destroyed. Yuya guesses "six," but Pierre activates the Trap Card "Card Chute", allowing him to increase the ATK of a monster he controls by that of a Level 4 or lower "Quiz" monster and then return the latter monster to his hand. "Quiz Sphinx" gains ATK equal to that of "Quiz Monkey" ("Quiz Sphinx": 1000 → 3500 ATK) and "Quiz Monkey" returns to Pierre's hand.
Since Yuya answered incorrectly, all of his monsters are destroyed. Yuya activates the Trap Card "Performapal Curtain Call"; this turn, a monster he controls cannot be destroyed by battle or by card effects, and it gains 600 ATK for each "Performapal" monster that is destroyed during this turn. He selects "Odd-Eyes," and all of his other monsters are destroyed. ("Odd-Eyes": 2500 → 4300 ATK) "Odd-Eyes" attacks, and Pierre attempts to activate the effect of "Quiz Sphinx", but the effect of "Curtain Call" negates it. "Quiz Sphinx" is destroyed, and the effect of "Odd-Eyes" doubles the battle damage since "Quiz Sphinx" is Level 5 or higher. (Pierre 1300 → 0)
