Damn that sucks. At least we get everything else, though.

His only appearance is in a 2D cutscene, which can't have their sound extracted.

I couldn't find Sideshow Bob in here by name. Is he just in a folder that I'm missing?

Hello, all! I decided going surname then forename would work a little better for organisation since it groups families together, but maybe it doesn't make much difference. And then there's characters who either don't have a surname or their full name is too obscure or inconsistent to bother with. So if it's a bit much, Ctrl+F should help.

Due to how this is split based on only character, some of the archives get a little big, most notably Homer's. Unfortunately it would be too much of a pain to split each character based on level, since in this version of the game there is no distinction between files for each level.

For information on which characters are in each level, see https://simpsonswiki.com/wiki/The_Simpsons_Game#Levels. There doesn't seem to be a list of characters who are available in free roam, but the general rule is that most characters are but level-specific characters are not.

If you are after sound effects and short sounds from characters, I couldn't get them out of the Xbox 360 version, so they are at https://www.sounds-resource.com/playstation_2/thesimpsonsgame/.

And no, nothing about this game is canon. Wacky characters I've listed as who they represent. For example, the sumo wrestlers in Big Super Happy Fun Fun Game are clearly versions of Comic Book Guy, so that's who they are listed as.

This isn't exactly the best game of all time or anything. It's enjoyable to play through once, but replay value feels limited. You'd honestly not be missing out on much just watching a playthrough on YouTube. I'm impressed by the variety of characters in this game though, so it's certainly good from a Sounds Resource perspective.
