After Jane was introduced, Mika was afraid she was being replaced, and attempted to remake herself in a more interesting color scheme. ("Leslie" was my pseud on the board.)
She also used a magic spell to turn herself into a neko-style kao, although it wore off quickly, leaving her dizzy.
Finally I (seen here in exciting Mouse-Drawn-O-Vision) reassured her that I wasn't going to get rid of her, no matter what she looked like.
However, Mika realized she liked the half-updated color scheme, and decided to stick with it from then on.
