...Different Destinations - S3-E5
Other mistake: While in the past on the Jocacean Memorial Planet, Sub-Officer Dacon is sent up on the wall by his commander. Then, when the Venek Horde are coming over the wall Aeryn pulls one down and throws him to the ground, and we can see an armor piece lying on the ground, with the name "Dacon" written on the inside of the prop in English.
Revealing mistake: In the last scene of the episode, Angel kicks the guy out of the glass building. This guy's a vampire, and you can see his reflection in the glass windows. Vampires aren't supposed to have reflections.
Your Shoe's Untied / Squid's Day Off - S2-E2
Character mistake: In "Squid's Day Off", a wide shot shows Mr. Krabs exiting the hospital, except the building says" ENEREENCY" instead of "EMERGENCY."
Continuity mistake: The package Nigel holds in his arms near the beginning of the episode completely changes between shots.
