THIS. WAS THE HARDDEST. PROJECT EVER. TO BE MADE BY ME. (not just in the Mario Colors series, out of my WHOLE entire library of projects) Whew! Okay. Arrow keys to move. And none of your slime powers work in boss stages. >:D To beat Yoshi, I'll give you a hint: What's red, wet, looks like a punching bag, and is in your mouth? Oh, and to win, you HAVE TO download.
