The Psychic is a character that appears only in the episode "Séance Shméance."
The Psychic is a green fish with wavy black and purple hair. She wears a golden crown or tiara with a light blue medallion in the center, a golden necklace, earrings that look like fire, and a purple dress.
She starts in the episode when she disturbs the ghost complaining why he was disturbed. The Psychic replies, "Because, you keep forgetting to replace the toilet paper roll!" The ghost then says it wasn't him and that he states that Gale has done it. After this, Squidward finishes watching the show saying it is cheesy.
