Mouser shows up too! And yes, HIS FIGHT IS BETTER TOO! He throws Bob-Ombs at you that you have to throw back and he jumps back and forth between platforms. What’s impressive about Mario Mix’s boss fights is, unlike many ROM hacks, you can’t see the “seams” of where they modified existing stuff within the game code to create a slightly new thing. For the life of me, I can’t imagine what existing Mario 3 things the bosses were built out of to play as well and as new feeling and fresh as they do.
