Aussie retailer ‘USA Foods’ has brought over some of the Super Mario Amiibo cereal. They’ve got it in stock both online and at their Moorabbin store in Victoria. It’s only in limited quantities, so definitely head over to the website (on physical store) if you’re after a box. It’ll set you back $8.99.
The Super Mario Cereal has Amiibo functionality, but it doesn’t add a whole lot to the game. It’ll just give you some coins or other random items.
