The Flintstones may have met many strange characters in their day, but this is the first time where Fred and Wilma's relationship almost came to an (albeit brief) end. As the title suggests, Rockula and Frankenstone are The Flintstones version of the iconic horror monsters - just with more "Yabba Dabba Do!"
After Fred wins the big prize on a game show, the Flintstones and the Rubbles find themselves in Rockula's castle, with Rockula and Frankenstone now wandering around. Rockula wants to take Wilma as his bride, and she agrees.
But when Wilma asks Rockula to move to Bedrock and do daily chores around the house, Rockula decides to ditch his "long-lost love" for the bachelor life with Frankenstone.
