It comes in many different flavors, including lime green, red, orange, blue, purple, and brown. There is a blue label in the middle with the word "fiz" transcribed in purplish-red letters and illustrations of bubbles, as well as a blue cap on top. Although the bottle reads "Fiz," SpongeBob reveals its name to be "Fizz Bomb Cola."
It is shown to make its consumers belch in loud volumes.
When staying for a sleepover at SpongeBob's house, Patrick watches SpongeBob increase in width and loudly burp upon consumption of Fizz Bomb Cola's contents, which ends up interrupting Squidward's sleep. Patrick then consumes the cola himself and loudly burps through his eyes while SpongeBob is trying to get rid of the noise by putting headphones on.
