Sooo, back to this for a bit.....since I had an idea today.
In my story, Bucky and his crew will find themselves often on Earth, and on one occasion he will send Jenny to keep an eye on Willy while the rest of the crew...do something, I dunno. To blend in human society better and make sure she can stay close to Willy, Jenny learns a spell that will make her look as human, be it by looks, touch, smell, anything, to any human around her (Willy is the only one who can see her true self), and enrolls in his school as transfer student. However, while her spell works on humans perfectly, it can't fool machines like cameras, so she has to be careful when going through areas where there's video surveillance. Her looks have attracted a lot of boys of course, and some of Willy's former bullies often try to suck up to him so they can find out stuff about her, considering the fact she lives with him. XD

Just to show how she looks like to those who don't know of this character, the kitty on the right: http://www.furaffinity.net/view/6408486/
