In "Apple Thief," Tree Trunks calls the Banana Guards to turn herself in for stealing her own apples. When one answers the phone it says "Banana Guard speaking," suggesting that they don't have individual titles. Two are dispatched to arrest Tree Trunks, one of which makes the observation "this place could use a scarecrow" leading Finn to solve the mystery of the missing apples.
In "Princess Cookie," some Banana Guards stand around Princess Bubblegum as if they are barricades and some are even laying on their sides for that purpose. One of the Banana Guards disguises himself as a horse to trick Princess Cookie into coming out in a ruse, saying he will be allowed to leave without repercussion. Later in the episode, a large squad of them is sent to capture Princess Cookie; the guards move quickly and with picturesque coordination. They also arrive at the scene of the cookie's attempted suicide and take pictures, presumably for evidence. This, in addition to their role in "Apple Thief," shows that they perform policing roles in the Candy Kingdom in addition to their job as guards.
They also maintain a cavalry force as seen in "Reign of Gunters." Their unusual mounts resemble pink jellybeans with two woman's legs and wear red heel shoes.
Captain Banana Guard is their leader, whom Princess Bubblegum calls when she is about to send them into the hostage situation after Princess Cookie. No details are known about the captain yet.
The Banana Guards look like bananas with chocolate poured on top, along with some pieces of what appears to be sugar. They are taller than most characters as displayed when they tower over Princess Bubblegum. Their feet are popsicle sticks and they hold long bronze sticks topped with diamond-shaped gems that have similar color to the crystals on their head. While they look like popsicles, they are actually bananas that have popsicle stick legs.

- As there are no law enforcement vehicles with sirens in the Candy Kingdom, the Banana guards can be heard making the siren sounds themselves when responding to a call out.
