We are recruiting!
Banana Guards are Candy People who guard Princess Bubblegum's Castle and Princess Bubblegum. The Banana Guards always appear in pairs prior to the episode "Princess Cookie," but due to their role in that episode, it's clear that there are a large number of guards that all wear the same banana peel armor. The last known leader of the guards was Root Beer Guy (prior to his death) after his predecessor, Captain Banana Guard, was either dismissed or demoted due to incompetence.
Duties
Guards
As hinted from their names, the Banana Guards' primary purpose is act as guards in the Candy Kingdom. They are usually seen in the Candy Castle as its security guards. They also act as bodyguards for Princess Bubblegum and prison guards for the Candy Dungeons. The Banana Guards also operate and monitor the surveillance system that are prevalent throughout the Candy Kingdom. The banana guards also provide security for the Candy Vault.
Emergency services
Banana Guards have the responsibility of providing the basic emergency services for the Candy Kingdom, primarily in law enforcement. This is shown in "Apple Thief," when 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.
Military
Along with the Gumball Guardians, the Banana Guards are responsible for the kingdom's security and defense. They are shown to maintain a cavalry force as seen in "Reign of Gunters." Their unusual mounts resemble pink jellybeans with two stereotypical woman's legs and wear red heel shoes. They also have elite units with jet packs and insulated suits ("Reboot").
