While Jeb Jab may sound calm and collected in his voice, he can get pretty agitated and angry at points, willing to unzip Scott Wozniak's jacket and verbally asking for a restraining order. Starting in Animal Crossing: amiibo Festival | The Dark Age of Nintendo, Jab has shown a liking towards the video game series Gex.
Jab firsts meets Scott Wozniak when he enters the V.A.G. house, seen drinking "vegan coffee". While Scott Wozniak is introducing himself, Jab notices something suspicious about him and unzips his jacket to reveal a gallon of milk taped to Scott Wozniak's body.
Jab appears in every episode of the sub-series as someone who is invited over by Scott Wozniak to play "bad" Nintendo first-party games from 2015.
In the first episode, Jab shows up to New Location McGee when Wozniak falsely informs everyone coming that they will be playing Gex: Enter the Gecko, a game Jab has shown a liking too, when they will, in reality, be playing Animal Crossing: Amiibo Festival.
In the second episode, Jab shows up to New Location McGee under the same condition as the first episode, except that they're playing Mario Tennis: Ultra Smash instead of Animal Crossing: Amiibo Festival.
In the final episode, Jab is invited over to New Location McGee to play Chibi-Robo! Zip Lash, however, Jab mishears Wozniak's message and believed that they would be playing Gex. Later when the main cast of the episode go in the sewers to retrieve the copies of Chibi-Robo! Zip Lash that Wozniak has thrown down his toilet, they're attacked by an unnamed monster comprised out of copies of the game. Jab was the first to be captured by the monster, as he believed it was Gex and that it would be harmless.
Later when Jab (along with the rest of the captured) are freed from the sewer monster, they go back to New Location McGee where they talk before they decide to play Gex: Enter the Gecko, which Jab's expresses heavy interest in. However upon playing, Jab doesn't recognize the game.
In The Trial
Jab arrives at New Location McGee to discuss the lawsuit against Steel Wool along with Scott Wozniak, Rex Mohs, Terry Lesler, and Wendy's Employee. After a carpool, they (along with Steel Wool) arrive at the courthouse, named The Litigation Station.
Jab is the second person to be called to the stand, where's he's questioned about the veganism of being murdered by Steel Wool's lawyer, Liza Lotts, which Jab responds to by saying that he believes it allowed. Lotts criticizes how being murdered is allowed in veganism, which Jab agrees with. Lotts proceeds the cross-examination by saying that Jab's and the others' accusations against Steel Wool hurt him, which Jab apologizes for. Lotts ends the cross-examination by asking Jab if he thinks Steel Wool murdered Jab and the others, which Jab answers by saying that he doesn't.
During Scott Wozniak's cross-examination, Jab, Terry Lesler, and Mohs discuss how the 6 justices of the Supreme Court may show up at the trial as Mohs had prior connection to them. Jab joins the conversation by saying that he also knows the justices of the Supreme Court, as they're cousins. Lesler then realizes that due to their connection to the justices of the Supreme Court, they can threaten Steel Wool into confessing. The threat works and Steel Wool admits to the murder of Jab, Scott Wozniak, Lesler, Mohs, and Wendy's Employee. The unnamed presiding judge then proceeds to sentance Steel Wool death.
In Memory Cards
After being invited and arriving at Scott Wozniak's Halloween and pumpkin party, Jab is questioned by Scott Wozniak if he went as a doorway pirate (which Wozniak assumed due to Jab wearing a pirate hat), however, Jab corrects him and says that he went as Gex. As Jab is about to enter New Location McGee, he's stopped by Wozniak who says that Jab can't enter unless he has fruit. Jab attempts to be let in by showing the attendees of the party lemons, cantaloupes, and oranges, however, he's rejected with each fruit. Jab then shows Wozniak a memory card for the Xbox 360, and Wozniak lets him in.
When talking about memory cards, Wozniak suggests that they should check the data on pre-owned memory cards Wozniak had bought, which they do. Upon checking two Nintendo GameCube memory cards, the attendees of the party find out that they have the same contents, which they find "odd". They then check another memory card, where they find save data from The Legend of Zelda: The Wind Waker. Upon opening the save data, they find that the first save file inside the game is named "hELP", which Wozniak thought could be a code for the name Jim. They proceed to check another Nintendo GameCube memory card, and once they open it, they found out it has 15 and possibly more saves of Vivarium's 2006 game Odama.
After checking the 4th memory card, Rex Mohs suggests that they should leave New Location McGee, which all the other attendees agree with. Upon attempting to leave, the door closes and locks, which Wozniak believed was due to a rat.
After finding out that memory card support was removed in later models of the Xbox 360, the attendees run into Wozniak's room while screaming. After discussing what to do, a memory card is stabbed into Wendy's Employee's leg, killing him. After discussing more memory cards, Mohs says that the events remind him of outside. Wozniak then, after hearing Mohs talking about being outside, believes that if they get the ghost outside, they'll be able to stop it. Terry Lesler then says that if they want to bring the ghost outside, they need to stun it with something "big, bulky, and orange." Wozniak realizes that the pumpkin he had bought from the Lesler Pumpkin Orchard fits Lesler's description, and uses it to stun the ghost. After Wozniak stunned the ghost with the pumpkin, Mohs attempts to throw the ghost out of a window, however, he misses his first throw due to the mirror over his face obstructing his vision. After successfully throwing out the ghost, Wozniak ends the party.
- Prior to The Great Mysteries of Gaming, Jeb Jab's full name was never known, only being referred to as just "Jeb".
- As stated by Scott Wozniak in a Reddit AMA, Jab is less of a "hardcore vegan" than Terry Lesler.
