This is a reproduction of a low quality jpeg of a screencap from the Super Mario World cartoon intro. I had to make a few changes, but it's more or less the same. I love that shot and that intro. It's just so cute, and I like how Mario, Luigi, and Yoshi are drawn in that style the best. I have the intro on my comp, and I'd been meaning to redraw that shot for at least a couple of years, even though I didn't get to it until yesterday. I also have a wallpaper version, my current desktop.

Original image by the animators and background artists, I guess
I heard the reason the animation/artwork for the show's intro looked different from the actual show was because it was animated in Japan, while the rest of the show was animated elsewhere. (In fact, you can kinda tell, by the way Peach's mouth is drawn, and stuff.)
