The Check-X Quiz (called Tick-X Quiz in the British English version) is a true-or-false test Mario must take at the beginning of Mario & Luigi: Dream Team. It is run by Broque Monsieur and is located at the Pi'illo Blimport. When the brothers first arrive on Pi'illo Island, Broque is about to host the 612th annual Check-X welcoming quiz. Due to Luigi knocked unconscious near the blimp, Mario must take the quiz alone. Two questions are asked for the entire quiz:
- Zis island is named Pi'illo Island. (True)
- Zee leader of zis island... he is called Dr. Sneezemore. (False)
The true question must be answered by talking to the staff Brock on the green panel, or the true panel. The false question must be answered by talking to the staff Brock on the red panel, or the false panel. Mario wins five coins for each question he answers correctly, for a total of up to ten coins.
