An even rarer sighting in Mario's third outing is the elusive white treasure ship. if you've ever seen this thing before, then it was probably out of sheer chance, because the conditions to unlock it are extremely specific. Kudos to the tireless Mario obsessive who figured this one out... How to unlock it: End a level with an even number on the clock Make sure the number of coins you have is a multiple of 11 Make sure the '10s' digts of your score correspond with the number of coins you have, so if you have 11 coins, you need the digits to be 10, if you have 22 coins, you need them to be 20, and so on. Do all the above in either Worlds 1, 3, 5 or 6.
