Plot
Trivia
- Pidge says to the robots, "Let's find out how you can do against one little Earth man". A later episode reveals that he (and Chip) grew up on Planet Balto. This apparent contradiction can be explained if Pidge and Chip were at least descended from Earth immigrants to Balto, if they did not themselves immigrate there with their adoptive parents.
- Princess Allura said that she had been to the tomb many times. In the original source material, Princess Fala never visited her father's tomb.
