Shelby
Shelby and Kent seem to have a close relationship, as they are both brothers.

Trivia

 * Kent carries 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 fact that in some species of earthworm, when a segment is cut off both sections can regenerate into two worms.
 * Kent is Shelby's nickname for Butty.
 * 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.
 * He might be named after current head writer Kent Osborne.
