It took me a minute to figure out what you were talking about but that one was meant to be a zipper! (The triangle part being the pull and the zig-zag part being the teeth) That was one of the ones I drew for the original version of this like 5 years ago and didn't bother to redraw so maybe it's a little hard to parse...
Oh that one is supposed to be an antler! Though personally I think it's fine if you interpret any of the shapes however you like, coral could be cool... (and your saying it also looked like a stick reminded me I meant to put a leaf in here but forgot to. I will have to try to remember that whenever I update this next.)
I'll consider the idea of making a list of everything that's in here though! It would be a bit long and hard to maintain if I update it though. (I was vaguely considering putting the source code up somewhere, so the list would maintain itself in that case if it was just all the files, but I'm still kind of confused by software licenses so I haven't done that yet...)
All the colors are made of randomized RGB values! So that's just a funny coincidence (in my experience it feels like I get the French flag from it a lot...)
