There's a stack of trivia I started last year, and I am still working on it. It is known as "Who Wants to be a Mariomerchandiseaire!?" I made it extra hard, and so far I have 7 rounds. There is no prizes, and it's just for fun. The round starts as like "For 100 Coins" and the answers are multiple choice. Maybe I'll put one round per week!
If you think you're the biggest Mario fan (I know I'm one of 'em, and a smart one too!)
Answer this question:
Who is the guard (sort of) in the Mushroom Kingdom castle, and also Toad's friend?
and
In Monster Mix-Up, how did Mario and Toad have to open the door?
