Sandy is an intelligent, scientific, bipedal anthropomorphic squirrel who resides in Bikini Bottom and is featured as a close friend of SpongeBob SquarePants. She is from Texas and it is for this reason that she is seen speaking in a Southern accent, and is proud of her home state which is frequently brought up throughout the course of the series. She has been shown to possess a number of tough, tomboyish character traits and interests; she is skilled at karate and frequently enjoys practicing it with SpongeBob, she is shown to be an excellent bodybuilder, is a rodeo champion, and possesses extraordinary scientific skills and can construct complex inventions. She must wear a spacesuit when underwater with a helmet in order to breathe, and vice versa when SpongeBob, Patrick, or any other sea creatures visit her tree-dome. While Sandy is normally portrayed as kind, helpful, and understanding, she has been shown to possess a vindictive side too.
