SpongeBob hires this fish as to follow one of the Krusty Krab's 'secrets' as told by Squidward. He is hired as the grill cook and is seen in this position even in the end of the episode.

"Escape from Beneath Glove World"

  • Throughout the series, Incidental 105 is constantly ripped off or scammed out of money.
    • In "Bucket Sweet Bucket," he complained about the new price of twenty-five dollars for a Krabby Patty but decided to buy four anyway when he liked the new decor.
    • In "The Clash of Triton," Bikini Bottomites were going to watch King Neptune eat for five dollars, but Mr. Krabs didn't want to give change for a twenty.
    • During the episode, "Yours, Mine and Mine," he was going to buy the new kids meal for just two dollars only to get Mr. Krabs to double it.
    • In "Kracked Krabs," there was a video showing Incidental 105 being ripped off by getting charged three times for a bag of chips with triple flavor.
    • In "Once Bitten," despite that he was bitten, he somehow managed to survive the infection therefore he never became a zombie. He was able to stand upright as well. He is seen in the mob of survivors that are using the Krusty Krab as a safe zone.
    • In "Gullible Pants," he walked into the Krusty Krab, and SpongeBob went up to him, stating that he knew his secret. Not wanting his secret to be revealed, as his words to SpongeBob were "What! Who told you?!" he follows SpongeBob to the kitchen and begins to grill the patties.
