There's captions, be sure to click them. Sorry about no audio. :C
Flying white fangs! Evolving World is basically a world you can create. You set the mobs, it's HP, drops, background, BGM (hence why the BGM in this is Opening Theme Song). Of course though, it's balanced & limited. So you can't make your mobs drop Empress Weapons, lol. Oh, and the flying white fangs. Apparently any mob in this specific map (there's a couple of maps in your evolving world) will fly.
