Mr. Lunt is a decorative gourd with a moustache. He often wears a beige safari-like hat and uses the brim for expression. In the Netflix series, he looks relatively the same, but now wears a white suit and has an additional goatee, and he no longer has a gold tooth.
He is the only main character to crossdress more than a few times.
Much like Pa Grape, he is one of the few characters to not have any visible eyes.
During the pre-production of Big Idea's second feature film, Mr. Lunt's outfit was initially designed to more closely resemble his classic pirate attire with his forehead covered. Universal requested that Lunt would be given eyes to let him show more emotion as a character. After having artists experiment with various concept sketches of him with eyes, the Big Idea team ultimately found the designs very unappealing. In the end, it was decided Mr. Lunt did not need any eyes for the film.
He was villainous in some episodes, but he was good in most episodes.
In Mr. Lunt's own love song His Cheeseburger, it was revealed that Mr. Lunt doesn't have any eyes whatsoever.
Phil stated on Twitter that the backstory of Mr. Lunt's golden tooth was that "it was part of his gangster outfit (even in his debut appearance) and it stayed with him."
It is unclear what Mr. Lunt's first name is, as a fan asked Phil on Twitter about Mr. Lunt's first name assumed to be "Karl", and Phil states that it probably should be "Mister".
Of all the redesigns, Mr. Lunt’s is the most minor.
