Lord Reginald is one of Sandy's bosses who only appears in the episode "Chimps Ahoy."
He is a light brown monkey with a black hat and a black jacket. He also wears a light green shirt and a green tie. He has a British accent and he wears glasses.
He, along with Professor Percy and Dr. Marmalade, leave the bus that stops at Sandy's Treedome. Professor Percy introduces himself and then Dr. Marmalade and Lord Reginald. SpongeBob and Patrick show the three their invention, the Automatic Back Scratcher, Hair Comber, Nose Picker, and Ukulele Tuner 9000. The three are unimpressed and want to see a demonstration of the invention to see if it works. Patrick chooses Lord Reginald to test the invention. Patrick straps him in. He asks Patrick if it is safe. Patrick says that he is as sure that it is safe as he is sure that he is a doctor professor. Patrick starts the machine. Professor Percy asks if Lord Reginald is alright. Inside the machine, the machine removes Lord Reginald's hat, combs, and cuts his hair. He thinks it is splendid The machine then scratches his back. The machine then starts to pick his nose. He describes what the machine is doing. He then says that the machine is feeding him pudding. SpongeBob says that he does not remember that part of the invention. The machine then tries to tune Lord Reginald's ukulele. When that fails, it starts going haywire. It hits Lord Reginald with the ukulele, hits him in the back of the head, and then starts taking other parts of the invention to attack him. It does so and he screams. Dr. Marmalade asks if he is alright. Lord Reginald just screams. Sandy hears the screaming and runs into the treedome. Soon, Lord Reginald is shot out of the invention. Professor Percy asks if Lord Reginald is alright. The three decide to stop Sandy's funding. The three are about to leave when Dr. Marmalade needs to eat a banana. He takes one out. One of Sandy's inventions, the Fully Automated Nutcracker, starts up. It is laying on a log nearby. It takes the banana and peels it. Dr. Marmalade is surprised. Professor Percy tells Lord Reginald to test it again. Lord Reginald takes out a banana and it peels it. The board of directors says that it must be the banana peeler that they have been searching over a hundred years for. They start acting like animals who are excited. Sandy's bosses take back what they said about her losing her funding and they give her another 20 years of funding. Lord Reginald wonders if Sandy can make the poop flinging machine that has been eluding them for years. Dr. Marmalade says, "Now. Now. One miracle at a time." The three primates leave.
