 The Gruesomes are a family consisting of married couple Weirdly and Creepella, and their son Goblin (Gobby for short).Also living with the Gruesomes is Uncle Ghastly who is only seen as a hand and a shadow in "Meet the Gruesomes" and a hand coming from a well (that punches Fred Flintstone in the face) in "The Hatrocks and the Gruesomes" (he is also heard for the only time as a terrifying and creepy laugh in "The Hatrocks and the Gruesomes").They first appear in an episode of "The Flintstones" titled "The Gruesomes".
