There are many things that people don't know in the Mario World, or you do know it, but you don't relize it. For example, how many bowsers are there, and, how many castles are there to fit all of those. How old is the original yoshi? Even when Mario and Luigi were babies, he looked exactly the same as when they are grown up. What happens to items like mushrooms, fire flowers, and stars? Does he quickly eat them, or does he somehow absorb them. Same with coins, does he quickly put them in his pocket?
