Pearl Sinclair is the sister of Earl Sinclair (Husband of Fran Phillips single's surname) , she's left Earl and her parents to pursue a career as a contry singer/musician.

Yep, the actor's/puppeteer's who act/move as her use the same suit as Earl with a hat, some makeup and a dress, Dolly Parton was big in the 90's so make Pearl with some monster Jugs.

Maybe you can make Earl using her LoRA.
