Stinky Cheeks is the new evil and an alternate version of Sandy Cheeks. Her only friends are ScumBob and Patjerk and sometimes Slickward. Everyone else is afraid of her. She lives in New Bikini Bottom and is one of Sandy's clones.
She switched places with the real Sandy Cheeks during Seasons 4, 5 and 6. Stinky replaced the real Sandy Cheeks during Seasons 7 and 8. In Season 9 the real Sandy Cheeks returned and they both switch places again like in Seasons 4, 5 and 6.
Stinky is obsessed with science while the old Sandy Cheeks was obsessed with karate. So you can easily tell the difference. She has a ripped off personality from Jimbles Notronbo. Stinky Cheeks also works at a strip club and robs community centers. She sometimes sends ScumBob and Patjerk on hideous missions. She is the result of Squidbob because of the molecular transporter being unstable.
