New Super Mario Bros. Wii Walkthrough Part 4: Fixed!

There, I updated my last few parts by correcting myself right off the bad with the koopa kids, lol! Plus I demonstrate my cropping technique and why it's better than leaving it unedited. But from here on out, I'll crop the parts properly where they need to be cropped. I found a easy technique to do it. While doing that, I clear out the first three stages in World 2!

Annotation correction corner:
