since there is truckload of moomin implications bending, i prefer to not touch the tags but moomin should be a species tag since its the name of the species and the_moomins should be the copyright tag instead because its the name of the franchise. trust me, im finnish and i know this stuff.

I can go through the tags and make it so in a bit, bit busy now.

And done.
This thread should clear up the mess: https://e621.net/forum/show/145504
