I've experimented using this method while speedrunning the level trying to find a faster route a while ago and was only able to find a few things. It either didn't load parts of the level to finish it or I needed peter to finish part of the level.

I don't speedrun this game anymore but I'm sure someone will find something.

you have resparked my interest in this game again ill see if there is any other spots that will be clippable

i would also like to ask what version of the game you were playing and if it was on emulator?

I was able to do it on PS2 on a emualtor. I havn't tried pc but I guess it would work the same unless it depends on framerate. I know games that glitches work differently depending on framerate like 25/30 on console and 50/60 on pc. But because it's an animation clip, it wouldn't matter on framerate. Thus working on all consoles.
