The Plath family outgrew its humble roots, and so did the show’s title.  Our refresh for Season 4 of TLC’s Welcome to Plathvillle is saturated with worldly blush. Country sky and bonnet blues shift to a city skyline of amethyst and spicy coral, as the Plath’s transition in lifestyles.  Fivestone’s new main title paints the evolving relationships as the family further splinters and the older children seek fame over a simple life on the farm.
