Jeeves

Jeeves is a giant sentient fork who works and owns his own restaurant. He first appeared in SMG4: Mario's Fancy Dinner where he helped Donkey Kong with his date with Pauline.

He later appeared in SMG4: If Mario was in... Baldi's Basics, where he is a math professor, and immediately quits over Mario and his incompetence.

Jeeves reappears in SMG4: Stupid Mario Tennis Aces as a referee for tennis. During the video, he is Waluigi's coach to prepare him for the Aces tournament.

Jeeves again reappears in SMG4: Stupid Mario Paint, painting the "Mona Toadsworth", a version of the Mona Lisa with the face of Toadsworth.

Once again, he reappears in Mario and the Waluigi Apocalypse where he works as a journalist during the GlitchCon incident and T-Zombie pandemic. He ended up being infected by a bunch of T-Pose Zombies.

His most recent appearance was in SMG4: Mario And... The Well, where he had the idea to hoist Fishy Boopkins out of the well using the rope.

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.

Donkey Kong
Jeeves does his best to serve The Dong during his dinner date with Pauline, only to have the evening ruined by Mario's antics.

Mario
After Mario refuses to leave the restaurant and stains Jeeves' suit, Jeeves reluctantly recruits him to serve DK in his place. Mario ends up serving a pile of garbage for dinner, causing Master Dong to fly into a fit of rage and chase after Mario with a sword.

Waluigi
Jeeves is Waluigi's tennis coach.
