From the center of your body, a blob begins to form. To an observer (Not that there are any), the blob would appear shapeless, but little would he know about the changes being made there. Soon, but not soon enough, the blob burst, sending a horrid monstrosity into the world.
It has the shape of a fish, covered with armour plating. However, several tentacles (both poison and not) sprout from it, along with leaves to help feed it. And what a hunger it has. A hunger, partly brought by the fact that it has no intestines (It is your first try), forcing it spew its wastes out of its mouth. In other words, don't kiss it. Not that it would ever care, for instead of eyes, it has only hollow pits, and instead of seeing, it smells out its prey, no matter where it is hiding, from whence it will strike with lightning speed, due to its hyponome! (Also, no radula)
