Sandy Cheeks

Sandra Jennifer Olivia "Sandy" Cheeks (born November 17) is one of the ten main characters in the SpongeBob SquarePants franchise. She is an American squirrel from the surface who wears a diving suit and lives in an air-filled glass treedome to survive underwater. She is voiced by Carolyn Lawrence.
Sandy is a thrill seeker who loves extreme sports and karate. Having come from the state of Texas, she has a Southern drawl and a love for rodeos. She works as a scientist and built both her treedome and air suit and helmet herself. She is also a member of the Gal Pals along with Karen, Mrs. Puff, and Pearl.
== Background ==
Sandy first meets SpongeBob in the second half of the show's first episode, "Tea at the Treedome". After he helps her fight off a clam, Sandy invites SpongeBob over for lunch at her house, though SpongeBob does not realize until after he has arrived that she lives in an airdome. However, flashbacks in The SpongeBob Movie: Sponge on the Run and the prequel series Kamp Koral: SpongeBob's Under Years appear to contradict this, instead showing Sandy having met SpongeBob and Patrick at the eponymous camp. The Kamp Koral episode "Kitchen Sponge" explains this discrepancy by revealing that Sandy had her younger self sent to camp as a way of stopping Plankton from stealing the Krabby Patty formula at that point in time.
