A jelly is composed of an amorphous substance which causes it to obtain a nearly elastic use of energy- the transfer of both potential and kinetic energy is almost instantaneous, with a minor degree of interference. However, the body itself magnifies the energy, causing the jelly to shake. Therefore, if you drop a jelly, it wibbles and wobbles for hours.
II. The Lifestyle of a Jelly
Jellies rarely have more than two life goals-- the two most basic ones are to be happy, through varying forms, and to make others happy. This simple command-direct attitude doesn't allow for much flexibility. Thus, the emotions of a jelly often are directly reflected in their actions. A jelly with a 'murder and get plastered' protocol will rarely ever strive to obtain happiness for another.
III. The Reproduction of a Jelly
Jellies lack a means of procreation; instead, they divide and multiply not in the way a virus or asexual race would, but in the way you would divide batter or cookie dough. The newly formed entities are merely a compilation and seperation of the mixture of the initial creating elements of the original jelly; therefore, at any point in time, a new jelly could be created and populate the world, if enough elements existed. In fact, if the jelly were to never be seperated, it would created a gargantuan jelly. Scary thought. o_O
IV. The Communication of a Jelly
Jellies are able to communicate through simple noises, facial expressions, sound effects, bodily vibrations, changes in temperature, color, speed, a rudimentary language, and singing effects. While there is rarely a universal consensus between what each of the expressions means, it is generally thought that when a jelly is bubbling rapidly and burping acidic bubbles, it is best to put your head between your legs and kiss your bum good-bye.
