Toad: "Whoa, Mario, you just can't go out there arms swinging. Who do you think you are Bruce Lee?"
Not Toad. Mallow. Another quote of Mallow's was when Valentina and the Shy-Away were talking about Mario...
Mallow: VALENTINA!! HAND OVER THE KEY!!, NOW! [sic] (Mallow trips as Mario climb a small set of stairs to approach Valentina) Ack!
Valentina: How utterly rude! And who in blazes are YOU anyway?!
Mallow: Me? I'm the REAL prince, that's who!
Valentina: Brat! And how DARE you listen in on a private conversation...!
Mallow: Private? PRIVATE?! Everyone in a 10 mile radius could hear you!
EDIT'D: Got the exact quote.
