I actually caught the Platinumfish the other day. I'm only missing three now; King Marlin, Phantom Flutterfly, and Gold Hercudrome. Been real busy catching them since I got the game as well as taking lore notes.
I've uploaded Gastodon's Icon, the fauna icons are way too small, due to jpeg crunching they lost a lot of detail which makes it harder to work with them, so those may need to wait until I have a large window of free time, same for the Gajalakas and Grimalkynes, I wonder why those don't show up in the monster list, along with Female Kestodon/Gastodon (IF the latter actually have a female variant).
We appreciate your desire to help out, but I (and some actual staff members) think that you should first look into improving your english skills, as any wiki, you are still welcome to participate in discussions, and if there's any bit of info you'd like to add to an article, I recommend seeking a friend who can help you structure the text properly.
