This is my noncommentary playthrough having played/reacted to the game already for trying to get 100% Completion in the tutoriallike manner I provide. This video covers Chapter 6, which also contains a penguin detective.... well, a penguin who claims to be a detective. I thought there was going to be a murder on the train, but then I remembered that this is a Mario game, rated for all ages.

Some areas of my memory were a bit foggy while playing this, I apologize for stalling sections. Then again, I do have the timestamps. I probably would've edited the stalling sections out, but *insert excuse here*, and I didn't want to keep pushing the video back. It's like pushing a ball up a hill. If you stop midway, the ball will roll back down, but if you keep pushing, it will come all the way.

For the Prince Mush Superboss fight, you basically have to superguard to win. That might be why this is a superboss, which aren't meant to be required. I planned to cut out my failed attempts when editing the video, but I happened to get lucky and defeat him on my first go recording this. I will have to see how I do against the final boss, as that's hard in the sense of heavy damage numbers.
