A Japanese retailer’s careless reveal of their Mario Tennis Aces pre-order bonus has led to the discovery of 3 new and unannounced characters.

The characters in question can be spotted in the bag below. Can you figure out who they are?

Guys check it out, some of those character emblems are Diddy Kong’s and other characters we haven’t seen yet! I wonder this image means? #MarioTennisAces @GameXplain @AndreSegers @AshPaulsen @Pacific1fun @AbdallahNATION pic.twitter.com/9toxmy8KPi

There we have it – Diddy Kong, Birdo, and Red Koopa Paratroopa! This isn’t the first time new characters have been discovered by accident before their official reveal, and it may not be the last.
