Actually in order to get the correct statement from that we have to go into the KH Formula. This is often shown as a ratio of how badass things get when they enter the KH Universe.
Original 1:4 KH
This means that Mickey Mouse became Four Times as badass as he usually is. Since Bugs is on a different level than Mickey in reality he's much more Badass in KH probably meaning that he runs his own world and most his friends are nigh invincible. What with all the sometimes darker humor they've grown used to Heartless being around and hearts return to their bodies almost the moment they step on Bug's world.
The problem is no one's gonna swarm Bugs or Mickey, because everyone knows people play Kingdom Hearts for the Final Fantasy people. It makes one kind of sad, but hey. And Bugs' expression IS good. You even got the freaked out hair on top thing done! Bugs is most hilarious when he's in a tough spot.
