Role in episode
She is a witch who lives in the Badlands outside of Bikini Bottom. SpongeBob and Patrick think she is the one Squidward says to find, when he was really referring to the "Desert Sandwich." The sand witch is revealed to have worked in an evil deli, as she creates a monster-like sandwich which brutally beats up Squidward.
Her name is a play on the word "sandwich" and also stems from her former occupation as a deli worker.
