Do you know the name of the Tv show with the alien named evie and her father was like a cube of light or something??

Out of This World

"Out of This World" (1987) (http://imdb.com/title/tt0092423/)

I couldn't remember this show either but the theme song was "Would You LIke To Swing On A Star".

There was an old disney movie about something like that, andI remember the girl was afraid of the rain and hid under the car, and then she was in the sink and transformed into water and the human girl freaked out. Hahah. It's not Alex mack, that was a show. Idkkk.
