Shelby and Kent seem to have a close relationship, as they are brothers. Shelby worries about his brother due to the fact that he thinks he's too young, but Kent showed him that he could take care of himself.


  • Kent carried a green margarita sword, but it broke after he first tried to defeat the Rat King.
  • He's actually Shelby's butt who's come to life, based on the myth that when a segment is cut off from an earthworm both sections can regenerate into two worms.
    • However, there is a real species of worm that can regenerate when cut in two, the planarian.
  • Kent having to return to the Dewdrops after partaking in their food is similar to the myth of Persephone and Hades. Persephone is tricked into eating pomegranate seeds from the Underworld and is forced to return every winter.
  • Kent's name is based on Adventure Time writer and storyboard artist Kent Osborne.[3]
  • Kent's sword, forged by the Dewdrops, is named Punch Party. It is revealed at the end of the episode that Shelby kept it, along with the Rat King's teeth.
