Volcano Sauce Drop is a character that only appears in the episode "Karate Choppers."
He is a shiny drop of Volcano Sauce who is red with grayish eyes and has an evil look on his face.
When SpongeBob and Sandy are fighting, Sandy pulls out SpongeBob's tongue and is about to pour Volcano Sauce on SpongeBob's tongue. SpongeBob is scared and imagines a face appearing on the drop of Volcano Sauce and saying, "Heheheheheh! By the powers of naughtiness, I command this particular drop of hot sauce to be really... really... HOT!" SpongeBob gives up and Sandy drinks the whole volcano sauce bottle.
