One of Our Dogs Is Missing. Kids and dogs. Always a winning combination. Wish Upon A Star visits the theme of “Something For Nothing” and how such bargains usually end. Lots more great expression! Look at her, bottom right, when Smith brings in the device; looks like she’s sharing a private moment with Bill Mumy, visible in the next shot. Penny cheats, and is caught, you can see practically the whole script in her face.
Penny!
