The hoopla fish is a very small, light green fish who wears a light purple shirt and indigo footsies and has dark green fins. He can open his mouth to a large diameter. His only spoken line is "Hoopla!"
The hoopla fish continually interrupts the narrator of the "Krusty Krab Training Video" every time he is going to say "Sounds like a lot of hoopla to make over a little Krabby Patty, right?" After the hoopla fish shouts and cuts off the narrator far too many times, he gets hit with a brick.
In the Spanish version, he says "Hurra!," which translates to "Hooray!" in English.
In the European Spanish he says "Bombos y platillos!",which translates to "Drums and Cymbals!"
