Sandy is a close friend of SpongeBob SquarePants. She is a proud Texan and speaks in a stereotypical Southern drawl. In order to live underwater, she resides in a bubble-like dome and wears an atmospheric diving suit when outside her house. Conversely, as revealed in Tea at the Treedome, other characters must wear “water helmets” with opposite functionality when visiting her house. Sandy possesses extraordinary scientific skills such as the ability to construct complex inventions. Sandy is shown to possess a number of tough, tomboyish character traits and interests; she is skilled at karate, engages in bodybuilding, and is a rodeo champion. She is also a close friend of Patrick Star, SpongeBob’s best friend and neighbor, though she sometimes gets annoyed by him.
