It was during the first season of Lost in Space that it seemed that Penny and The Bloop were almost inseparable! Usually wherever Penny was The Bloop could be found! I used one of Angela Cartwright Unruly Shadow Stamps in the back ground.
I did this in watercolor with Lumiere. I do think that bloop was my least favorite character in Lost in Space! I can't think of even a guest star that was worse than the bloop ... unless it was the dragon in The Questing Beast.
