Did something for the fairy trio idea.
The Burrunjo didn't quite seem enough like a fairy type so I added some jabberwocke traits (the green colors, the stripes on the tail, the pointless fins). The idea is that it breathes a mist the same way a normal dragon would breathe fire. The mist engulfs and confuses opponents, giving it the element of surprise (kind of in reference to how they apparently disappear in a mist)
Not much to say about the Yowie...It's just a big sasquatch thing...didn't really change it that much.
I feel like the fairy type just doesn't suit the bunyip that much, so I tried going with the Billyo, which is apparently the Australian equivalent to the unicorn with horns made of silver that comes out during the night, running almost faster than the eye can see.
