The Hoopla Fish is a very small, light green fish that wears a light purple shirt and indigo footsies. He can open his mouth to be of large diameter. His only line was, "Hoopla."
The Hoopla Fish continually interrupted the narrator every time he was going to say, "Sounds like a lot of hoopla to make over a little Krabby Patty, right?" After the Hoopla Fish shouted and cut off the narrator too many times, he got hit with a brick.
In the Spanish version, he says "Hurra!" which means "Hooray!"
In the German version, he says "Hoppla!," which translates to "Oops!"
He is very popular on YouTube for memes and YouTube Poops.
