Johnny has also been the announcer at other events, such as the 21st Fry Cook Games. He was the narrator of the King of Karate video in "Karate Island," the narrator of the championship "boxing" games, and voiced the loudspeaker at the Bikini Bottom Zoo in "The Smoking Peanut." In addition to announcing events in Bikini Bottom, Johnny also serves as a news anchor for the Bikini Bottom News. Most of the news reports he gives are regarding disasters in Bikini Bottom, such as in "Wormy," where he warns the town about the "monster", and in "Nasty Patty," when he reports the warning of a man who pretends to be a health inspector to obtain free food. He also appears in the episode, "Safe Deposit Krabs" where he announced the opening of the Bank of Bikini Bottom Bank.
The only times where he has ever interacted with the main characters (as he usually only appears on a screen) are in "No Free Rides" and "Procrastination," and both of these were during dream and fantasy sequences. His voice is often heard when he himself is not shown, so it is uncertain if he is speaking during these instances, as in "No Free Rides" and "Suction Cup Symphony," his voice is different from his usual one. He also appears during the theme song, when the line "Then drop on the deck and flop like a fish" is sung. Doug Lawrence voices him, except for when Tom Kenny voiced him in "Suction Cup Symphony" and "No Free Rides", when Dee Bradley Baker voiced him.
