Sandra "Sandy" Cheeks is a land squirrel who
lives in a treedome. Unlike most of the other characters in the
series, Sandy is not a sea creature. She and SpongeBob's
relationship is a love-hate one, since they don't always get along
often. Sandy is a very smart, talented and athletic squirrel who
came from the U.S. state of Texas, who moved to Bikini Bottom in
the South Pacific Ocean, because her job is that of a scientist
experimenting underwater and creating inventions. Sandy is
SpongeBob's closest friend after Patrick.
