|List of characters|
Giant Demonic SpongeBob is a character that appears only in the episode "Ghoul Fools." When Squidward was sucked into the void by Lord Poltergeist, this creature is who Squidward encountered. He looked a lot like SpongeBob, but instead of a high-pitched voice, he had a deep, slow-motion voice. In the first part, he appeared in the Void and scared Squidward. In the last part, he appeared at the Kursed Krab, working there in the void by flipping the restaurant. Then his head morphed into the Flying Dutchman's, and he started laughing.
- His voice and laughter sounds much deeper than SpongeBob's voice.
