Back at the start of November we had the Super Smash Bros. Ultimate Nintendo Direct. Throughout the Direct we were introduced to Piranha Plant, the pre-order fighter that must be redeemed if you purchased the physical edition of the game, how do you redeem it though?
Before I get into how to exactly redeem Piranha Plant, it should be noted that if you purchased a digital copy of Smash Ultimate then Piranha Plant has already been redeemed for you, and you can skip this entire process. Assuming you have a physical copy of Smash Ultimate, you will firstly need to go to your home screen on your Switch, hover over the Super Smash Bros. Ultimate and press the + button on your Switch. This will open up an options menu where you will see at the bottom "My Nintendo Rewards Programme", select this option and then further select "Earn Points (game card verison only)".
Selecting this option will activate the redeeming process of Piranha Plant, which will then send a confirmation email to your email account linked to your Nintendo Account. From here you want to navigate to whatever email address you have linked to your Nintendo Account and find the respective email from Nintendo. Once that has been done, click the "redeem now" option provided in the email, this will redirect you to the Nintendo website where you will be asked to enter your Nintendo Account password. After this is completed Piranha Plant will be redeemed and you will await your download once the fighter is released.
It should be noted that this manual redeeming process has an expiry date, players that do not redeem their copy of Smash Bros. Ultimate before January 31st will have to purchase Piranha Plant individually. As the fighter is not apart of the Fighters Pass DLC pack.
