A clever Texas squirrel that has to wear an oxygen tank to breathe underwater.
Sandy is a squirrel from Texas who lives in a special treedome near Bikini Bottom. Her debut episode was Tea at the Treedome.
Over the course of the series, Sandy is shown to be something of an adrenaline addict and highly competitive. She is frequently shown practicing Karate with SpongeBob in the episodes Karate Choppers and No Weenies Allowed and in the song in Party Pooper Pants, dreams of skydiving in Sleepy Time and practices several extreme sports, as shown in Pre-Hibernation Week.
However, despite her interest in extreme sports, Sandy is also shown to be an intellectual. In Sandy's Rocket, Chimps Ahoy, and Patrick Smartpants, Sandy is shown solving mathematical or scientific problems, as well as being an inventor for her monkey bosses.
SpongeBob is certainly in love with Sandy as in several episodes he has been seen to be jealous of other creatures - particularly Larry the Lobster - when Sandy seems to be doing activities with Larry. However, the creators of SpongeBob SquarePants claim SpongeBob to be asexual.
Sandy finds SpongeBob to be a mishap as evidenced in Sandy's Rocket. She is annoyed by him in a similar way that Squidward is annoyed by SpongeBob. She gets angry at him often. In The Great Snail Race she kicks SpongeBob's butt for saying stuff behind her back. In Ripped Pants she leaves him to play with Larry.
