SandraJennifer "Sandy" Cheeks is one of the main characters in the SpongeBob SquarePants franchise. She is a squirrel from the surface who wears a diving suit and lives in an air-filled glass treedome to survive underwater due to her nature as an air-breathing creature.
Sandy comes from the state of Texas, known from the episode of the same name and exhibits many characteristics of a cowgirl character. She speaks with a heavy Southern accent and uses typical Southern slang words and phrases, such as "howdy" and "y'all."
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 insults about Texas and violently attacks them when they continue to insult it.
Sandy is one of the most intelligent and levelheaded 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 Professor Percy, Dr. Marmalade, and Lord Reginald. As an inventor, Sandy is capable of creating extremely advanced devices with ease. Her inventions include a manned spaceship, a teleporter, a submarine that can shrink to microscopic size and go inside a person's body, a robot in "What Ever Happened to SpongeBob?," and even a Protogenerator 2000 cloning device in "Overbooked."
Sandy is also very athletic and physically fit. She and SpongeBob share a favorite hobby 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 joins her in on occasion, most notably in "Prehibernation Week." Sandy possesses immense strength. She is often seen at Goo Lagoon, 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 an intense daily exercise routine. In the same episode, she wins the eighth annual Goo Lagoon Anchor Toss competition, tossing an enormous anchor 510 yards.
Sandy is most commonly seen wearing her suit for oxygen when she is outside of her treedome. The suit is white and has a yellow patch with an acorn on it. It also has two red, and a blue, ring(s) on each sleeve. The suit comes with a big glass helmet with a pink and yellow flower on it. She also wears boots with one red dot on each side of them.
When Sandy appears inside her treedome, she wears purple clothing, primarily a purple bikini top and a purple and green skirt-like bottom. In "Someone's in the Kitchen with Sandy," when her fur pelt is off, she wears a purple bra and purple panties.
When she is on her exercise hamster wheel, she can be seen wearing a white hoodie and blue workout sweats.
At night, she wears a nightgown. In "Sandy's Rocket," she wears a light blue nightgown and is shown for a split second until the camera cut to her face. In "Karate Choppers," she wears a lavender nightgown while karate-chopping over the phone with SpongeBob. In "Survival of the Idiots," Sandy wears a pink nightgown throughout the episode. In "Overbooked," she wears a purple nightgown while giving a presentation to her colleagues.
She's dressed up as a goldfish in "Scaredy Pants", but only her head resembles a fish.
Sandy is usually kind and caring for SpongeBob and is known to help him out when he's feeling lost, as seen in many newer episodes, such as "Lost in Bikini Bottom." However, in older episodes, she is shown to be much crazier. In "Prehibernation Week," she is shown to be crazier than ever when she forces SpongeBob to play dangerous games, thus leaving him to run away. She then forces all Bikini Bottomites to search nonstop for days on end looking for him, to the point when they all run and hide from her just like SpongeBob did.
Sandy takes full pride in her Texas heritage and shown with her Texan accent. She had a lot of experience there and won't stand any insults of it, as shown in "Texas," where she cries several times throughout the episode because she missed her old homeland and even made a song dedicated to it. SpongeBob and Patrick then make fun of the state. She is offended by them mocking Texas, and thus she chases both of them down and brutally attacks Patrick.
She has also been shown to have a strong competitive streak and a high opinion of herself. In "Sandy, SpongeBob, and the Worm," she completely ignores SpongeBob's warnings about the Alaskan Bull Worm and tells him that she is "too Texas tough," only to discover the hard way that the Bull Worm is indeed too much for her to handle. In "Pressure," she continuously brags that land creatures are better than sea creatures and nearly drowns herself in an attempt to "prove" it.
In "Survival of the Idiots," Sandy is shown during her hibernation as an obese, monstrous version of herself since prior to going into hibernation, animals must have tremendous amounts of body fat and energy reserves to survive the winter. SpongeBob and Patrick enter her snow-filled treedome and disturb her sleep, and the semi-conscious Sandy viciously attacks them, believing them to be Dirty Dan and Pinhead Larry, two outlaws from her dreams.
She can be overly competitive, which is best seen in "Squirrel Jelly", where she even harms her friends due to her competitive nature.
In "Texas," Sandy lassos Patrick and attempts to do the same to SpongeBob for "taking the name of Texas in vain."
In "Survival of the Idiots," while half asleep, she beats up SpongeBob and Patrick and puts them in graves, mistaking them for Dirty Dan and Pinhead Larry, as they woke her up during her hibernation and took away her fur to keep warm.
In "The Great Snail Race," Sandy kicks SpongeBob's butt for making a sexist remark. Sandy is arrested in a deleted scene from the episode for doing this. She also engages in a fight started by Patrick in "Band Geeks."
In "Squirrel Jelly," Sandy got carried away with her competitive side and caused physical harm to most of her friends.
In "Prehibernation Week," she plays very extreme sports games with SpongeBob against his will; he then hides from Sandy, and she forces every last Bikini Bottomite to look for him. She even refuses to let them take a break.
In "Kenny the Cat," Sandy frequently talks badly about Kenny and accuses him of fraud. Once Kenny is helped by SpongeBob, she reveals in front of all Kenny's fans that Kenny is a fraud, humiliating him. Later in the episode, while Kenny is conversing with SpongeBob on how to regain his celebrity status, Sandy kicks Kenny up to the surface before he can figure out how to be "special" again.
In "Patrick SmartPants," he kicks out Patrick after he calls Sandy stupid. This shows Sandy's narcissistic side.
In "SpongeBob You're Fired", she makes experiments which people eat. However, these experiments have a very bad result. A fish's head puffs up, and Patrick grows another Patrick on his head. The thing Sandy did was also illegal.
Abilities and talents
Sandy is smart, athletic, and talented, and therefore has many skills, such as:
Karate: Out of all the characters in the show who practice karate, Sandy is the best at it; she has green karate gear.
Science: Sandy has shown to have a vast knowledge of science: several episodes feature her doing experiments. As the series progressed, she did more and more science.
Singing: Sandy is a very good singer; the episode "Texas" marks the first time she is shown singing.
Guitar: Sandy has played guitar while singing several times. Also, in the episode "Band Geeks," she is the lead guitarist of the band.
Lasso: Sandy can throw a lasso very easily, such as in "Sandy, SpongeBob, and the Worm" and "The Gift of Gum." Also, in video games such as Battle for Bikini Bottom, she has the ability to throw her lasso to catch or even break things that are far away.
Gliding: In Battle for Bikini Bottom, Sandy can use her lasso to glide.
Bodybuilding and muscle growth: In "MuscleBob BuffPants," "Christmas Who?," "Karate Island," and "Whelk Attack," Sandy is shown to have huge muscles, and seems to get bigger and huge each time they are displayed, and growing at almost pure will.
When she was an adult, she joined a company called Treedome Enterprises. This company sent her down to Bikini Bottom to study the under sea life.
In Bikini Bottom, she met SpongeBob SquarePants while she was fighting a giant clam. She also met Patrick Star the next day when he tried to save SpongeBob who was at Sandy's treedome for tea and SpongeBob was all dried up because there is no water in her treedome. She has also met many other sea creatures since she arrived at Bikini Bottom.
Sandy lives in a huge polyurethane dome, which is known as the "treedome." It is an air-locked environment and contains no water, making the treedome the only place in Bikini Bottom where Sandy can survive and take oxygen without her suit. Its floor is covered in grass and it features a large tree, which contains Sandy's living quarters. The treedome also humorously includes a giant hamster wheel, among other backyard-like things. As seen in the episodes "Survival of the Idiots" and "Bubble Buddy," the dome produces snow during the winter, from which it can be assumed to simulate other weather patterns as well.
As seen in the episode "Wormy," Sandy has many pets residing in her treedome, including caterpillars, snakes, crickets, mice, and birds, among others.
The company that owns this and many other treedomes is the Tree Dome Enterprises Limited. Its board of directors, a group of chimps, came for an inspection in "Chimps Ahoy." Her old habitat was back home in Texas.
Sandy first met SpongeBob when he saw her wrestling a giant clam and ran down to save her. Since then, Sandy has been one of SpongeBob's best friends, and she enjoys various activities with him such as karate. She also enjoys going to Goo Lagoon with him and lifting weights. Despite their tight friendship, Sandy has gotten annoyed by SpongeBob in various episodes, such as "Sandy's Rocket" and "Texas."
Patrick and Sandy have a close friendship. They usually get along very well though Sandy has frequently been annoyed by Patrick's utter stupidity no doubt due to her higher intellect. On occasion, Patrick has angered her to the point where she has threaten to attack him, as shown in the episodes "Texas" and "Survival of the Idiots." In "Patrick SmartPants," she gets along well with Patrick until he gets a little arrogant and thinking that she's dumb.
Sandy and Squidward usually have little interaction, but when they are seen together, they usually get along, however there are times where Sandy can get annoyed by him. She is also shown to be happy to help him, such as in "Squidtastic Voyage" when she helps him revive his clarinet reed from his throat. Then in The SpongeBob Movie: Sponge Out of Water, she was seen carrying him to safety when he was almost crushed by skating humans, and letting him ride on her back when they're chasing Burger Beard the Pirate. At times like in the episode "Patrick! The Game," Sandy can easily get annoyed by Squidward's attitude towards things, like his attitude towards Patrick's game.
Sandy and Karen have become good friends, sharing an interest in science. The two meet in "Perfect Chemistry," and Sandy calls Karen beautiful. In "Frozen Face-Off," Sandy helps save Karen from being frozen. In "Salsa Imbecilicus," Sandy and Karen team up to create a university. In "Girls' Night Out," the two and Mrs. Puff spend a night out together, and the three refer to one another as "Gal Pals" throughout the episode.
Sandy tends to dislike Plankton, such as in "Someone's In The Kitchen with Sandy" when he steals her fur to obtain the Krabby Patty secret formula. However, they do get along in "Perfect Chemistry," as she is impressed by his lab and knew that Plankton was planning to steal the Krabby Patty formula. They are also seen playing chess together in "Mimic Madness."
Sandy and Pearl have a positive relationship. In "Bubble Troubles," Pearl helps Sandy breathe air, saying "I guess us mammals have to stick together." Pearl goes to Sandy's birthday party in the episode "Feral Friends" and wants her to stay in Bikini Bottom in "Texas."
Sandy and Gary barely interact with each other, but they do know each other. In "Culture Shock," Sandy says Gary has "such a way with words."
