Jeeves

Jeeves is a giant sentient and obsessive compulsive fork who is a boss of several companies and is a recurring character in SMG4 series.

SMG4: Mario's Fancy Dinner
In his debut episode, he is the waiter of the restaurant where he helped Donkey Kong with his date with Pauline. Although he had some trouble with Mario, it ended well for everyone involved.

SMG4: If Mario was in... Baldi's Basics
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.

SMG4: Stupid Mario Tennis Aces
He is shown as a referee for tennis and as Waluigi's coach in training him for the Aces tournament.

SMG4: Stupid Mario Paint
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.

SMG4: Mario and the Waluigi Apocalypse
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.

SMG4: War Of The Fat Italians 2018
He appears to assist Mario and SMG4 in their rap battle against Waluigi although he had no lines in it.

SMG4: Mario And... The Well
He appears after being called by Tari where he suggested using a rope to pull Fishy Boopkins out of the well. Although the idea worked, Mario let go, causing it to unravel.

SMG4 Christmas 2018: The Most Important Thing
He appears as an example to Bob of having someone to spend Christmas with, in his case Toadsworth.

SMG4: Mario Goes to the Fridge to Get a Glass Of Milk
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.

SMG4: Mario's Lemonade Stand
Jeeves opposes Mario's efforts to sell lemonade, as he has located his lemonade stand close to his milk cafe.

Personality
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.

Trivia

 * Unlike the other three original characters introduced in the past couple years, Shroomy, Saiko Bichitaru, and Tari, Jeeves gets much less screen time and appearances, only appearing twelve times after his debut (thirteen if the hallucination in SMG4: Mario Gets Stuck On An Island is counted).
