Man where do I even begin with this run? I guess the most important part is the out of bounds clip I discovered at the beginning. This is the first ever practical out of bounds clip in this game (the other one is in Ferb Level 8 where the giant robot can hit you through walls), and I'm super proud of finding this and even getting it in a run. Now, this clip is brand new so we don't exactly know how it works, nor do we have any other members of the community who can investigate it. But here's what I came up with:

I believe part of the reason the clip works is because of the way the platforms in this game are grid-based. By jumping in between them at a certain speed, there's most likely a slight break in collision that allows you to clip through it at a specific angle. I had another instance of this clip occurring in Perry Level 7 with 2 grids, which basically confirms my theory: https://imgur.com/nFXYoMc

This also potentially confirms that this trick requires you to be falling for at least a second for it to work, and also that it may only work with Perry. If all of this is correct, it may be possible to implement this specific clipping method in other levels, but I wouldn't count on it being done in runs since this is incredibly difficult to do. It was so difficult in fact that I wasn't able to get another run with it that wasn't Twitter compressed, which is definitely unfortunate, but at least there's surviving video.

So yeah, if you couldn't tell this is a pretty difficult and random run, so I'm incredibly happy with it.
