The Volcano Sauce is a light-red bottle with a light-orange volcano on it that appears to be erupting. It is shown on a light yellow rectangle that also says "Volcano Sauce" with "Volcano" written in black and "Sauce" written in red. There is a black rectangle on the side saying "HOT!" written in yellow text.
The Volcano Sauce is used in a few different ways. For example, Sandy uses it to drip it on SpongeBob's tongue in "Karate Choppers." In other cases, fish put it on their Krabby Patties or, in Sandy's case, she uses it as a beverage.
