This placed 3rd, so it's my design to keep.
The first canine head breathes fire, the cobra head is alive and functional. (The cobra head also has poison if you were curious and hisses.) The spikes on the canine neck is not a layering mistake, they grew from there NATURALLY. There also used to be a third head right next to the canine one, but it was defeated in battle. (It was a goat head.)
The three, now two, heads generally agreed with each other because they all wanted the same thing. Contrary to popular belief, they actually didn't fight each other when they wanted to go separate directions or during mealtimes. They just prioritized and waited for each other. If one head took too long to eat though, they'd get a bit hissy though.
They protect their territory fiercely.
This is an entry for a competition. Anyway, Tyki, this is my entry. I really like it, so if it doesn't place 1st, I'd love to keep it. ^_^
I left the male/female thing for you to choose, and same for the name.
(But personally, I think the creature as a whole is female.)
