Woohoo! I finally got to the rarely seen coin ship and I also finished a world with a second power-up! That coin ship can only be seen under certain conditions. I wanted to have it in this video, so I went to GameFaqs just to find out how to make it appear since, up until the last time I played through the game, I had no idea how I kept making it appear. The conditions are very strict and I'm glad that I managed to check that place before I started recording and got it to appear in this video since this is the last world it appears in!
Now on the the bad stuff. I did rather poorly on the second fortress. I don't know how I managed it, but I lost to Boom Boom. I still can't believe it. Up until that point, I've never been hit by him, so being defeated by him just kinda made my jaw drop for a few seconds...
