—Mr. Peanutbutter’s catchphrase
Mr. Peanutbutter, the star of Mr. Peanutbutter's House, is an anthropomorphic yellow Labrador Retriever who is BoJack Horseman's friend and former sitcom rival and a main character in BoJack Horseman. He dates and later marries Diane Nguyen.
Mr. Peanutbutter has yellow fur, a brown nose, a slim and muscular build, and according to model sheets he is 6 ft. tall. He always wears a grey V-neck shirt and aviator sunglasses, usually propped up on his head, with light blue pants with white lines going down the sides, orange sneakers, and two wristbands, a brown one and a neon green one, on his left wrist.
On "Mr. Peanutbutter's House", he had a tuft of combed down hair, and he wore a blue shirt with a 90s esque pattern on it, light blue jeans, and white sneakers.
Mr. Peanutbutter was in born on the Labrador Peninsula in rural Canada, and attended Northwestern University.
He first moved to Los Angeles in the early 90's or late 80's, where he ended up co-piloting the plane that brought him to California, which happened purely because he walked into a room without looking.
He was recruited onto the show with no previous acting experience, having wowed the show's director David Chase and the audience when he barged in on the pilot's live taping. The show's working title was Untitled Horsin' Around Knockoff, and BoJack Horseman was resentful of the show because he rightly assumed it was a knockoff. However, in 2014, they began a friendship when Diane Nguyen, Mr. Peanutbutter's girlfriend, began writing BoJack biography.
He took a long list of low-level cting gigs during the 2000s decade, and in 2014 he briefly filmed for a reality show titled Peanutbutter and Jelly. He falsely confessed to stealing the "D" from the Hollywood Sign to propose to his girlfriend Diane, in reality, BoJack stole it to try to win Diane back and to impress her, the incident inspired Hollywood's widely-acknowledged name change to "Hollywoo" as well as the film Mr. Peanutbutter's Hollywoo Heist.
He and BoJack's housemate Todd Chavez co-founded the company PB Livin, which resulted in several failed business ventures, including a Halloween store open exclusively in January, and Mr. Peanutbutter going deeply into debt. He took a job at a shoe store, where he was scouted for his comeback role as host of the game show Hollywoo Stars and Celebrities: What Do They Know? Do They Know Things?? Let's Find Out!.
In 2017 his ex-wife Katrina convinced him to run for Governor of California, during an effort to recall incumbent Governor Chuck Woodchuck Coodchuck-Berkowitz. Mr. Peanutbutter did so mostly out of vanity, even though he actually liked Coodchuck's policies, but eventually dropped out and endorsed Coodchuck. Katrina replaced him as a candidate with Jessica Biel (his other ex-wife), who went on to lose to Coodchuck.
Mr. Peanutbutter has been married three times. His first wife was Katrina Peanutbutter. They divorced in the late 1990's, because of her arrogant attitude and abusive nature. His second wife was Jessica Biel - she left him in 2007, and Mr. Peanutbutter first struck up a friendship with Diane Nguyen the same evening. Mr. Peanutbutter married Diane, his third wife, in 2014 after about seven years of dating. He and Diane nearly became parents, but decided to get an abortion.
Mr. Peanutbutter's demeanor is constantly energetic, nice, cheerful, kind, and playful. In short, he is a dog seen from the point of view of a cat person. Not only is he constantly positive, he is also a bonehead who has difficulty understanding metaphors or puns. This causes him to crack jokes that instead of being funny, just make people scratch their heads. This causes BoJack to testily try and tell him why his jokes fail, and how to improve them. A life of success, wealth, and fame has meant he has never faced any real challenges or have to make difficult decisions. He also struggles to see that Diane is coming on to BoJack. However, he is not as dumb as he might be letting on - as stupidity is part of his persona, and he can at times show hidden depth. Despite their rivalry, he cares a great deal about BoJack's opinion and admires him for his work on Horsin' Around. True to his breed, he loves tennis balls and has a trunk stuffed full of them, that he presumably finds in parks and hoards. It is also important to note that Mr. Peanutbutter is a very good boy.
Despite his overall positive nature, he does have an impatient and no-nonsense side to his personality. This can be seen in arguments with his wife Diane Nguyen when they are arguing over gun regulations on the news or getting irritated with BoJack Horseman when BoJack rejects his gestures of friendship because he finds Mr. Peanutbutter's happy-go-lucky persona irritating. He can be very headstrong and heavily opinionated at times especially in a heated argument to the point of being borderline defensive. There are also traces of nihilism in him.
