There aren't any CGs, just movies.
In my opinion it is not worth the effort to make 100+ individual, soundless GIFs when you can just play the game. That's why I'm putting up what's not as easily accessible in the game.
If you really want to make a GIF set or have the video extract then be my guest.

There are 3 types of files (MPG, WMV, OGG). OGG's the audio files so have them in the same folder if you want sound. The WMV's are the same as the MPG videos but bulkier, so I'm omitting them.
Quite a few of these ones don't come with sound.
