noise: XXXX

Here is my submission to the World Ends With You contest here. It is a noise, and is common but powerful. They team up to attack with their teeth and claws from the front and behind. Their hooves allow them to run quite fast and kick from behind. They can shoot uhhh something... from in between the spikes on their backs.
Please don't tell me how much they look like Heartles...
I hope I win!!! I worked quite hard on this!!
