We're used to seeing games changed/censored for their release in China, but the case with New Super Mario Bros. U Deluxe is a bit of a head-scratcher. For some reason, the POW blocks have had their design changed to what appears to be 000.
We have no official explanation as to why the change was made, but there's plenty of speculation floating around. Some think it has to do with removing any/all English words from games during localization, while others believe it might have something to do with POW also being known as a acronym for prisoner of war. Even odder, previous Mario games that saw release through the iQue in China featured unchanged POW blocks.
