The Hoopla Fish is a very small, light green fish that wears a light purple shirt and indigo pants. He opened his mouth widely when he yelled "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 one airing of "Krusty Krab Training Video," the Hoopla fish says nothing and gets hit by a brick.
In the German version, he says "Hoppla!," which translates to "Oops!"
He is very popular on YouTube for memes and YouTube Poops.
