Sandy Cheeks is a sea dome-dwelling squirrel who lives for action and adventure. Having attempted just about every death-defying stunt under the ocean, she's accepted the ultimate challenge: living underneath it in an oxygen-filled dome. Sandy is Bikini Bottom's only resident rodent, and the apple of SpongeBob's eye (the only thing under the sea he likes better than his job at the Krusty Krab). For Sandy, SpongeBob is the sea bottom's best stunt buddy, and when they get together, crash helmets and parachutes are usually required.
