Shelby

Shelby (Or full title: Shelby the worm that lives in Jake's viola) is a character in Adventure Time who makes his appearance in "My Two Favorite People" and later returns in "Video Makers." He can talk and lives in Jake's viola. When Jake needs help when Finn's not around, Shelby might be the one to help him with his problems (kind of like a therapist).

Appearance
As the picture shows, he's a worm. However, unlike the other worm characters, Shelby more closely resembles an earthworm. He gave an idea to Jake, which was to spend more time with Finn and Lady Rainicorn at the same time. This leads to the synopsis of "My Two Favorite People". He has the same tone of voice as Manfried. Shelby is voiced by Pendleton Ward, which can be noticed because he sounds like Lumpy Space Princess, who is also played by Pendleton Ward.
