Sandy Cheeks is a squirrel that was forced to live in the ocean called Bikini Bottom because, she did many crimes when she was in Texas. She created a treedome in the Bikini Bottom and changed her identity into Sandy Cheeks so, the squirrel police will never find her. Her real name was actually Sandgrain Chicklet.
When she was 4 years old, she fell down in to a hole. When she woke up, an evil Teletubby called Po hypnotized her to be evil. When she was completely hypnotized, she started murdering all the Oompa Loompa. Then she killed a girl named Justin Bieber that we're all happy about.
She is a squirrel with a suit and has no eyes. Creepy isn't it?
