Clarence

Clarence was a character who appears in "Ghost Princess". He was the lover of Warrior Princess until he killed her in a battle for her kingdom. Afterward he became a broken man and died after consuming too much cheese at a Squeez-E-Mart convenience store and exploded. Jake was at the mart at the time, and having witnessed the Softy Cheese explosion (and being covered in the softy cheese that Clarence consumed) he couldn't eat Softy Cheese for a long time. Clarence was buried in the neer-do-well section of the cemetery under a gravestone that read "Some Donkus"; he became a ghost who had no memory of his former life. He met up with Ghost Princess, and took her to see the Spirit Waves. Finn and Jake figured out it was Clarence who killed Warrior Princess (now Ghost Princess) by matching the remains of a dagger handle in Clarence's grave with the tip of a dagger in Warrior Princess' remains. Ghost Princess ascended to the 50th Dead World upon learning how she died. When Clarence couldn't come with her he frustratingly proclaimed that his life was "like a fart". Because these were his last words before he died, Jake remembered who the man at the mart was, resulting in Clarence remembering his death. Ghost Princess said that she forgave him, and he was then able to ascend along with her.

Trivia

 * Clarence's last words ,"My life is like a fart" is a play on the more conventional saying, "My life is like a farce".
 * "Donkus" is not his surname. When Clarence was buried, his name was unknown, so they labeled him as "Some Donkus".
 * It is not known how long Clarence lived for after the battle in which Warrior Princess was killed. The battle seems to take place amid the ruins of highways and wind turbines. The Squeez-E-Mart seems to be located in the same general area as the battle but during a period in the Land of Ooo contemporary to Finn and Jake. It is likely that Clarence was living in the area for quite some time after the battle before Jake witnessed his death.
 * Clarence's skeleton has a large hole in its ribcage, this is likely due to him exploding. Likewise, there are strange protrusions on the sides of his head where his "antler headband" fit around his head, showing that while the headband may or may not have been part of his body, the antlers were.
 * Clarence is voiced by Sam Marin, the same person who voices "Benson" in Regular Show.
