Beating Prince Mush in TTYD with 1 HP before Chapter 4!

In Paper Mario: The Thousand-Year Door, I battle Prince Mush before starting Chapter 4 with Mario being in Peril. I used two Mega Rush badges and a Power Rush for Mario.

To unlock Prince Mush, you have to beat Chapter 3 and do the trouble "Help wanted!". I heard you can also fight Prince Mush as early as the Minor League (second time) without having to fight your way through the Glitz Pit a second time, but this is something I did anyway before I got the email. Some sources say you have to beat the entire game first, but I became able to do this fight sometime after I went down to Floor 70 of the Pit of 100 Trials and left. You go to the champion room and he will be available as an Exhibition Match opponent, and your prize for beating him is his belt, another trophy for your Key Items menu.
