A few years ago, a big tree was found on the Green Planet. It was a small planet and also called a Vatermelon

One day vatermelon hit by other giant planet, collapsed and released alot of energy that the tree did not stop to producing alot of their seeds. Not being able to transform all this energy, the melon tree exploded after giving the so many melon seeds and all the little melon seeds were shattered into the solar system. Some ended up on Earth, others in space ships (we are also searching for them too). The radiation from the vatermelon planet and the energy released by the tree during its explosion mutated the all little melon seeds, giving them a different appearance. The little melon seeds landed in populated areas and blended in with the different species, adopting the different human appearance and style!!
