I would like to see a big platypus in game, so we can use it as a mount!
They are one of my favourite animals, and they are weird enough to fit right into Ashes. I wouldn't mind it being classified as an aquacktic mount, what with the webbed feet, duck bill and beaver tail.
I suggest they all get the poison spike ingame that only the males get in RL, to poison opponents with in combat.
Here's someone in a 3D modeling subreddit that made one, for those who want a rough idea what it could look like:

I'd want an even better looking one for Ashes though

And here's a video if you want to learn more!
