The Weenie Burger Boss is shown to be a large human with dark brown hair and a 5 o'clock shadow. He wears a standard Weenie Burger Manager uniform.
The Weenie Burger Boss first appears when Buster tells the viewers that once they get a job, they get a boss too. When Babs tries to make a good impression (where she literally does her impression of Darth Vader). The Weenie Burger Boss isn't amused by it, flicking the helmet off her head and throwing her inside as well. He first tells Babs to make the Weenies for Weenie Burgers and tells her to do it faster. When she does, he keeps telling her to go faster, up to the point where she mistakenly puts him in the machine and he becomes a literal giant weenie. He is placed in a box, and when he escapes, he grabs Buster and Babs (he also becomes human again in this scene) and tells Babs to work at the counter and see to the customers. Unfortunately for them, their customer is Montana Max, who gives both of them Heck. After seeing how rude Buster and Babs treated Monty, He fires them, which Buster describes to the viewers as "the perfect time to quit".
