Freaky Frankenstone (known earlier as Stubby Frankenstone) is the son of Frank Frankenstone and one of the recurring characters featured in the franchise of The Flintstones during the late 1970's and 80's.
Freaky Frankenstone made his official debut in 1979 in the episode "Fred and Barney Meet the Frankenstones" from The New Fred and Barney Show where his father Frank and the rest of the family just moved to Bedrock and opened up their own condominium which they dubbed the Deadrock Arms Condorstonium that was home to a large gaggle of monsters.
In 1980, Freaky along with the Frankenstones starred in the primetime special, The Flintstones' New Neighbors. Later, Freaky and his family finally received their own animated segment in The Flintstone Comedy Show focusing entirely around them. Fours years later, the Frankenstones made their final animated appearance in The Flintstone Funnies, however the show was mostly repackaged segments from The Flintstone Comedy Show.
In the episode "Fred and Barney Meet the Frankenstones" from The New Fred and Barney Show and The Flintstone Primetime Specials, Freaky (known as Stubby) is a short humanoid with beige skin just like his father, Frank, red eyes and black hair. He wears a green loin-cloth with a shaggy black vest and "shoes" which are just two slabs of stone tied to his feet via rope.
In The Flintstone Comedy Show, he is now grown up and has fair skin, dark brown hair, black eyebrows and black beady eyes, and he also wears a teal loin-cloth with a grey button and a black vest.
