[SMBX2] Custom Clown Car Bowser Boss Showcase

Yo! Now y’all, this is by far, the BIGGEST boss I’ve ever worked on, aside from Kaptain K. Rool. It took so long, but at last, I’m here to show y’all this very cool boss that I think y’all will like. Thanks to MrDoubleA for the lightning ray attack code and to King Dracalgar Law for helping me implement it
