KateLynn SquarePants is SpongeBob's twin cousin. She is sweet, can easily get into a panic and has claustrophobia. She looks like SpongeBob, except she is blue and has brown (sometimes pink) eyes. In KateLynn Meets SpongeBob, KateLynn got herself in a predicament when she got stuck in a wringer in her home. SpongeBob came there (accidentally calling her a "sir" once) and attempted to help her. After much struggle, he frees her, and thus a true friendship was formed between them.
