Swap Plot Flop is the fourth episode of Josie and the Pussy Cats. It first aired 3 October 1970.
The Pussycats are presented a chance to play before royalty in a desert kingdom. They, however, are only interested in Valerie Brown because she looks almost identical to their beautiful Princess Milwila, who has been kidnapped by the Evil Eye.
Valerie accepts the offer to help and takes her place until she is rescued. But she gets kidnapped as well, along with Melody Valentine, who has been hypnotized by the Evil Eye. The rest of the gang pursue and enact a crazy rescue plan as music and chase scenes follow as they find out who's behind the Evil Eye.
- Much of the plot borrows elements from an earlier Hanna-Barbera series, Arabian Knights, which aired as part of The Banana Splits Adventure Hour two years before this show aired.
