Ragtime Mouse is a special enemy you may encounter in forests throughout Gaia. When encountered he will be accompanied by an O and an X. He will ask you a true/ false question (hence the pop quiz) which you answer by attacking O for true and X for false. To win this trophy you must answer all 16 questions correctly and then encounter him for a 17th time.
He will appear a maximum of four times before the events in Burmecia, six or more times before the battle at the Iifa Tree, six or more times before gaining the Invincible airship. After that he will appear indefinitely until you answer all questions.
To get him to appear the best strategy is to enter a forest. Then tap the direction stick/ D-pad very lightly so that the forest isn't disturbed (but Zidane still moves). This will give you a good chance of getting into a battle with Ragtime.
