Super Mario Odyssey has a lot of moons to collect. There are 830 to be exact (with the option to buy more up to 999), and this is what happens when you collect all the ones that can't be bought.

If you don't feel like watching the video, however, here's the list:

  • Your ship's sail turns gold.
  • You can fight a more challenging version of the final Bowser battle.
  • You can launch fireworks from the top of Peach's Castle in Mushroom Kingdom.
  • And finally, the end credits show you a new postcard.
