Nintendo has announced that Petey Piranha and Shy Guy will be released as free content for Mario Tennis Aces next month.
Petey Piranha (a Powerful character) and Shy Guy (a Technical character), will be the rewards for those that participate in an online tournament next month (1st – 31st December 2018).
You will need to take part in a singles tournament to unlock Petey Piranha, or the new doubles tournament to unlock Shy Guy.
Worry not, though. If you can’t participate in an online tournament, every reward character will be unlocked for all players on the first day of the following month.
Mario Tennis Aces is now available exclusively for Nintendo Switch worldwide.
