Yes, number three is the lie. I unlocked it once, but I never actually went there. 99 floor dungeons are normally easy for me...

And... I'm guessing... Number 3? Number one is certainly possible, and you have video evidence for number 2, so.

My signature PMD Team consists of Me (Lucario), Temporion (Dialga), and Darkrai (???).

I have friends from only the U.S.

I once killed a Regigigas with a Shuckle.
