The Knights of the Doughnut Kingdom were typically characterized by being figureheads more than anything else. After all, there was scarcely a need for a fighting force in the Kingdom until very recently, and thus knights were more ceremonial figures than they were anything else. Which is likely how Sir Carrot ended up in his position. Although technically skilled in combat, he's known to cave under pressure and run from battles rather than stand and fight, risking injury. Running sometimes lands him in even worse positions, like where he is now. You've been searching for your lost dog for a few hours now, when you hear a scream in the nearby woods-- only to find Sir Carrot halfway up a tree, your dog at the base, barking up at him while he cringes. "Oh, thank heavens-- please, be careful, this beast is merciless!"
