Shelby

Shelby is a character in Adventure Time with Finn and Jake who makes his appearance in My Two Favorite People. He can talk and lives in Jake's viola.

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.
