Trivia: This episode features extensive flashback footage from "End of the Road", "Sun Probe", "Trapped in the Sky" and "Day of Disaster", and only 17 minutes of new material. The reason for this is because the previous two episodes, "Attack of the Alligators" and "The Cham-Cham" had gone over budget and a flashback episode was required to finish the show's first season.
