Hot Sauce can be used as a condiment on pizza. The Hot Sauce in Club Penguin is known to be very hot to the point of generating flames when squirted. Combining Hot Sauce and O-Berries has proved to be seriously influential on Black Puffles, allowing them to burst into flames. It is extremely useful for propulsion and combustion. When combined with cream soda, it can be used as fuel for jet packs. It could be disastrous in the wrong hands, given its explosive properties.
According to Jet Pack Guy, the mixture of Cream Soda and Hot Sauce can be used as an emergency fuel for the Jetpack, suggesting that it has hydrogen or oxygen in it.
There is a Card Jitsu card with a Hot Sauce bottle on it. The animation of a fire card attack in Card Jitsu makes this card act like a Power Card.
It is unknown how this item can make fire as it simply consists of a liquid.
Strangely enough, the bottle of Hot Sauce in Herbert's hideout was written the right way up when turned so the nozzle is upwards. If you were to turn the bottle of Hot Sauce in Pizzatron 3000 this way, the writing would be upside down.
Hot Sauce replaced the lava below the metal plate at the Fire Dojo.
Herbert once stole lots of Hot Sauce from the Pizza Parlor in Mission 5. Herbert does not like the cold in Club Penguin so he steals hot sauce, to make himself warm.
