I have a really dumb idea for a (theoretically long) meme run. Do I need a run of this first to show, or do I need to create it here and have it approved by mods so that I can create the parameters for the category extension?

The gist of the run is butt% - fill your Hyrule compendium (creatures and monsters sections) with pictures of the creature's butt, or as close to it as possible (looking at you, cold darner). Time ends when the compendium is filled with goofy cartoon animal booties. Could also have a NG+ category.

Edit: I probably should've read the first item in the forum first, but welcome any feedback anyway.

You need to get runs for 5 different people before you can send it to the mods and get it approved. If you make a route doc or a youtube video of you doing the run and send it to the #extensions channel in the BoTW Speedrunning Discord then maybe you could get 4 others to run it.

That sounds fun but also very long. Maybe make it so that you only have take a couple pictures of booties (you can decide the category of booty pictures) and people will be more likely to run it (including me).
