For some reason, nintendo decided the normal moon from the gamecube release wasn't quite as much of a wrinkly ballsack ass moon as they wanted. They fixed that and made it look far more like a wrinkly ballsack as per miyamotos orders. I respect the decision to make the moon look my grandpas withered sperm sack, but I personally prefer my moons sperm free.
Just extract this to the switch root and your game will also be ballsack free, probably.
