Sandy comes from the state of Texas, known from the episode of the same name, and exhibits many characteristics of a cowgirl character. She speaks with a heavy Southern accent and uses typical Southern slang words and phrases, such as "howdy" and "y'all."
Sandy is very fond of her homeland and its culture, as most notably seen in the episode "Texas," in which she was homesick and considers leaving Bikini Bottom to return to Texas. In that same episode, she takes great offense at SpongeBob and Patrick's negative insults about Texas and violently attacks them when they continue to make fun of it.
Most of All, you all should know Sandy love Peanut.
