Sandy comes from the state of Texas, she was actually born in Houston, Texas but she exhibits many characteristics of a stereotypical "cowgirl" character by going to every city in Texas. She speaks with a heavy southern accent, and uses typical southern slang words and phrases. She is very fond of her homeland and its culture, as most notably seen in the episode "Texas," in which she grows homesick for it and considers leaving Bikini Bottom to return to Texas. In that same episode, she takes great offense at SpongeBob and Patrick's negative remarks about Texas, and violently attacks them when they continue to insult it.
Sandy is one of the most intelligent and level-headed characters on the show. She is a multi-talented scientist and inventor, and originally came to Bikini Bottom to study sea creatures and their lifestyles. In "Chimps Ahoy", it is revealed that she is employed by a trio of chimpanzees from the surface, named Dr. Marmalade, Lord Reginald and Professor Percy. As an inventor, Sandy is capable of creating extremely advanced devices with ease. Her inventions include a manned space ship, a teleporter, a submarine that can shrink to microscopic size and go inside a person's body (Squidward the octopus'), and even a cloning device.
Sandy is also very athletic and physically fit. She and SpongeBob share a favorite pastime of Karate, and frequently fight each other for fun. The karate they use appears to be stylized to fit that of "play karate", as they both mainly fight with chops and kicks in a cartoonish manner. There also appears to be other forms of fighting in the series, most notably in Karate Island, where three other fish demonstrate unique fighting styles, (which looks more like stylized versions of Kung Fu rather than Karate).
Sandy also enjoys extreme sports and thrill-seeking, which SpongeBob also joins her in on occasion, most notably in "Prehibernation Week". Sandy possesses immense strength, and is one of the strongest creatures in Bikini Bottom. She is often seen at Mussel Beach lifting weights with Larry the Lobster, of whom she is a good friend, and other muscular fish. In "MuscleBob BuffPants," Sandy shows SpongeBob her immense biceps and intense daily exercise routine. In that same episodes, she wins the eighth annual Goo Lagoon anchor toss competition, tossing an enormous anchor 510 yards.
Appearance in UltimaEdit
Later down the line, Sandy returns to assist the Society during the Chaos Emeralds Arc revealing that she now possesses the Ultimagauntlets. How she obtained them has yet to be delved into, but will eventually be revealed soon. When the Ultimacrystal Arc began, Sandy replaced Squidward as the fourth member of Nicks group.
