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 the name with "volcano" written in black text and "sauce" written in red text. There is a black rectangle on the side, which reads "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.
Role in series
The Volcano Sauce first appears in "Karate Choppers." Its role is to use it to drip it on SpongeBob's tongue. Volcano Sauce Drop appears in this episode.
Its third appearance is in "SquidBob TentaclePants." It doesn't have any special role in that episode; it just appears as a normal hot sauce. It appears in the Krusty Krab when a fish watching SquidBob walk by him. He then questions himself if he was using too much of it.
In "Company Picnic," after Squidward gets pickle juice in his eyes, he tries to grab something that will recover his eyesight, but accidentally grabs a bottle of hot sauce instead and squirts it in his eyes, worsening his pain and even setting his eyes on fire.
