A dog starts to play with an experiment pod thinking that it was a ball. The pod grows in his mouth so he spits it out. The experimental looks like a cat. The experiment gets into a fight with the dog. Later, Lilo sees the experiment on they way home from hula class. She thinks it is at cat at first but on closer inspection she can tell that it is an experiment. No house cat has that colored fur. When she tries to take it home it starts to attack her out of fear but she quickly learns to hold it in such a way that it can't. She decides to take it to Jumba for treatment and to find out more about it.
When they get home Jumba treats the experiment and her arm. Jumba notices that it is experiment 009. Designed to hunt small animals, see in the dark, jump really high (be a house cat). Lilo decides to name it mouser. Lilo decides that it can stay with them until they find its one true place.
That night a black experiment with brown eyes heads towards thew cemetery to raise an army of undead. Luck ally, the experiment gets caught by the dog catcher first. She considers trying to escape but realizes that while she might be able to formulate an escape rout the best way would be to get adopted tomorrow. She could do that no problem.
Guess whats going on so far before I post my next chapter and win a fabulous prize. I'll let you choose the hula girl who adopts the black experiment, no red heads :p Also, I'll take into account how much data one gives. The first person to figure something out gets the credit. I have a hula girl in mind if nobody can guess. Finally, if you don't have an account give the vote with the data. The prize is no longer available by the way since I am adding a disclaimer anyways.
