Penny is confused as being a space princess.
Lost In Space generally gets several episode reviews and the fact that I am the first to review this episode (in 2016) seems to reveal that there is something wrong with this hour. Yes there is.
Granted, I am aware that there are many devoted Angela Cartwright fans reading this, and such fans might get a buzz out of this adventure, but for everyone else...Princess Of Space is back-to-season-two-campy- terrible.
Even Cartwright herself probably thought the episode was bad when she was acting in it as she revealed (in 1995's The Fantasy Worlds Of Irwin Allen) that "I liked it (LIS) when there was some sort of message, but when it got really silly...those are the ones (episodes) I don't like".
I can even say that this is worse than the soon to come Great Vegetable Rebellion (aka The Talking Carrot Show)...at least that gave Guy Williams some screen time.
Not science fiction, not clever fantasy like the Mr Farnum episodes, but just too stupid for words plot ideas that belong in I Dream Of Jeannie...not Lost In Space.
