Casey Kelp is one of the Snorks, a 1980s cartoon show that was inspired by The Smurfs.
In "Brian the Bachelor", she is having dinner with AllStar Seaworthy. She bends over and Allstar gets a peek at her panties, giving his snorkel an erection.
She is voiced by Nancy Cartwright, although in the original series she provided the voice of Daffney Gilfin, another Snork.
