According two the Nintendo 3ds facebook page.
Hey Mario Tennis Open fans!Did you know you'll be able to unlock top secret characters by using special QR codes?Like this post if you you'll be the first player to discover them all.

They could be talking about the yoshis but would they be top secret.

Well, this is a shame for those who don't have Facebook, but I'm sure it'll spread out eventually.

They could still be talking about the Yoshis, even though we have nearly all of them, but still, if there's secret characters, that would be awesome.

I hate Facebook.

Do you think this could be the sort of stuff that was on that hidden tab on the japanese website? Only detectives know...

This is discrimination for people who don't want anything to do with Facebook. >.>

I hope there are two secret characters to even things out.

If they were two add two more they should be rosalina and drybones.So everyone has a partner.
