The Hoopla Fish is a very small, green fish that wears a 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.
