"Meow. Do not be startled. I am here to guide you as we explore the deepest recesses of your mind."
- Mayonnaise, Split the Room.

Mayonnaise is a character in the Jackbox Party Pack series voiced by Tim Sniffen. He was originally revealed to be one of Cookie Masterson's cats in the You Don't Know Jack series, but has since become his own character and he now hosts Split the Room.

Appearances[]

You Don't Know Jack (series)[]

Mayonnaise was one of Cookie Masterson's two pet cats, only being mentioned in certain moments. One example was YDKJ 2011's Nocturnal Admissions with Cookie Masterson, where Poopsie and Mayonnaise appear in the backgrounds of certain questions. Yet it's not confirmed if it's the same cat.

Split the Room[]

Mayonnaise is the host of the game, being an anthropomorphic (and animated) grey-furred cat who presents the prompts in a style similar to The Twilight Zone. As players play, they may notice Mayonnaise's head morphing into things or changing styles while others are writing answers. As revealed by the credits, he was able to put it all together using some well-made props and video editing.

Joke Boat[]

Mayonnaise appears as one of the eight playable dummies in Joke Boat, taking up player 5.

Job Job[]

One of the selectable avatars is a silhouette of Mayonnaise, and when the applied votes are tallied, the sound byte of him saying "Roar" is played. Unlike most of his other appearances, this one appears to be quadrupedal.

Tee K.O. 2[]

Mayonnaise appears as a playable character in Tee K.O. 2, and was the 1st revealed character for #TeeKO2uesday. He wears a pink T-shirt, grey pants, and tiny black shoes, as well as striking a pose quite similar to Incineroar from his appearance in Super Smash Bros. Ultimate.

Fakin’ It All Night Long[]

Mayonnaise appears as one of the 10 playable characters in Fakin't it All Night Long, and is represented in a bikini.
