Jeeves is a giant sentient fork who is a boss of several companies and is a recurring character in the SMG4 series.
He is shown to be a math teacher although he quits early on although it is understandable as he had tried five times with teaching Mario math but they all failed.
He is shown as a referee for tennis and as Waluigi's coach in training him for the Aces tournament.
He is shown as a painter painting a picture of Mona Toadsworth, which was just the Mona Lisa with Toadsworth's face on it for his friend.
He is shown as an on-site journalist during the GlitchCon incident and T-Zombie pandemic. He naturally gets infected and turned into a T-Pose Zombie subsequently.
He appears to assist Mario and SMG4 in their rap battle against Waluigi although he had no lines in it.
In this episode, he appears as the Moo Moo Milk factory boss. Apparently, he is also shown to be a boss who ordered the overworking on the cows to give him milk.
Jeeves opposes Mario's efforts to sell lemonade, as he has located his lemonade stand close to his milk cafe.
Jeeves appears on line at the bank and gives Mario a Rubik's Cube to stop pestering him, but Mario ends up choking on the cube and coughs it up, causing the cube to hit Jeeves and throw him out of the building.
Jeeves appears in SMG4 Christmas 2018: The Most Important Thing as an example to Bob of having someone to spend Christmas with, in his case Toadsworth, hosts a cooking challenge in SMG4: 3 MILLION SUB FAN COLLABORATION!, and attends Desti's funeral along with Shroomy but does not talk in SMG4: Final Hours. Additionally, he appears in THE OFFICIAL SMG4 MERCH REVEAL alongside Toadsworth and a dapper Teletubby as well as a hallucination by Mario in SMG4: Mario Gets Stuck On An Island.
Jeeves seems like he cares only about honor and dignity, but he's also very interested in money, as we see when Donkey Kong asks him to kick out all of the other customers in the restaurant so that he and Pauline, DK's date, can be alone. At first, Jeeves politely denies DK this request, but when he's bribed with a bag of coins, he eagerly obliges.
He's also somewhat of a perfectionist, as indicated by his refusal to be seen wearing stained clothing, as well as his insistence that only the best players can join the Tennis Aces. He is shown to be an artist since he made Toadsworth a painting of him as a Mona Lisa parody.
He may also not care about personal safety, as shown in SMG4: Mario And... The Well, when he interrupted Shroomy's instructions.
