Instead of Bedrock, the locale is repeatedly given as "Rockville". Also, Fred's address is 345 Stone Cave Road, yet 13 weeks before in "No Help Wanted", (21 October 1960), it was 201 Cobblestone Lane.
This is the only time the Flintstone's car is shown with a trunk.
Wilma and Betty go looking for Fred and Barney at The Poiple Dinosaur, a dive located by the wharf that was known for attracting seedy, criminal types. The Flintstones would later have a pet purple dinosaur named Dino.
