Aboriginal Australian Dreamtime Mythical Creatures for Australian Region

Hey Guys!

I'm brainstorming ideas for an Australian based Pokémon Region that I'll eventually make, hopefully before Pokémon makes one themselves.

And for the 'box art' legends I wanna base them on traditional Aboriginal Dreamtime Mythical Creatures. I have one of them being the Rainbow Serpent. And the overall themes of the plot would be the flaws of Modernisation/Urbanisation.
