In the episode titled "Texas," Sandy wants to go back home to Texas, but in the episode titled "Chimps Ahoy," she sings a song saying that she wants to stay in Bikini Bottom rather than wanting to go back to Texas. She should make up her mind or if she had to leave in Chimps Ahoy, she could have just went back to Texas. I guess the creators havn't thought about the fact that Sandy's from Texas when they were making Chimps Ahoy.
