Shelby The Worm Who Lives in Jake's Viola
Name Shelby
Sex Male
Species Earthworm
Occupation Priest
Relatives Kent (Brother)
Introduced in "My Two Favorite People
Latest appearance "The Cooler"
Voiced by Pendleton Ward

Shelby first appears in "My Two Favorite People" and later returns in "Video Makers." He can talk and lives in Jake's viola. In "My Two Favorite People," he gives Jake the idea to hang out with Finn and Lady Rainicorn at the same time. He has the same tone of voice as Manfried. He also makes a cameo in "What Was Missing" when he crawls in and out of Jake's viola, and narrates the ending of "Holly Jolly Secrets Part II," where he and the general cast watch videos and wear sweaters. In the winter, he wears a green sweater with two candy canes on it. He appears in "Five More Short Graybles" reading a book while sitting on Cranky Cookie's statue, and has a major role in "Mystery Dungeon."

It should be noted that Shelby appears as an earthworm, and although earthworms are hermaphrodites he is a male as confirmed by Pen Ward.[1]


As the picture shows, he is a worm. However, unlike the other worm characters, Shelby more closely resembles an earthworm in color and shape. He is the color pink and has black eyes.



Finn and Shelby are friends. In the episode "Video Makers," Finn formally refers to him as "Shelby, the worm who lives in Jake's viola." Though in the episode "Mystery Dungeon," he actually talks to Finn as a friend. After Finn lost his forearm in "Escape From the Citadel," Shelby was seen crying, and curled up on Finn's leg to comfort him.


Jake and Shelby are friends since he lives in Jake's viola. In the episode "My Two Favorite People" Shelby gives Jake helpful advice. He is an actor in both of the movies Jake attempts to make in "Video Makers" and "The Pit."


Kent is Shelby's little brother, so they are close. Shelby told Kent to fight bad guys leading to Kent being an adventurer and defeating the Rat King. He appeared sad when Kent had to return to the Dewdrops.

Tree Trunks

Shelby and Tree Trunks appear to be friends. In the episode "Five More Short Graybles," he said hello to her. In the episode "Mystery Dungeon," they appeared to be friends and had to work together alongside Ice King, Lemongrab, and Neptr. Shelby was the only one whose name she pronounced correctly.


Shelby never interacted with Lemongrab until "Mystery Dungeon" where they work together alongside Tree Trunks, Ice King, and Neptr. However, they must be comfortable with each other because Shelby rides on his head for part of "Mystery Dungeon."

Ice King

Shelby never interacted with Ice King until "Mystery Dungeon" where they work together alongside Tree Trunks, Lemongrab, and Neptr. In general, he was annoyed by Ice King's myopia, desperation and selfishness, particularly when it was revealed Ice King had knocked the others out to be brought to the dungeon in an effort to get the Ancient Sleeping Magi of Life Giving to bring his Fionna and Cake fan-fiction to life (Shelby was particularly annoyed, as Ice King had planned to use him as fish bait, plus he would have brought something to be brought to life had he known). Later, as Finn and Jake watch Ice King and Neptr pretend Fionna is around in Ice King's Imagination Zone, Finn wonders if there's anyone sadder than the Ice King. Shelby responds with a dry, "Me, watching this."


Even though they both live in the Tree Fort, Shelby never interacted with Neptr until "Mystery Dungeon" where they work together alongside Tree Trunks, Ice King, and Lemongrab.

Unnamed girlfriend

In "Wake Up," Shelby mentions a "G.F." for whom he wishes for a pony from Prismo, instead of wishing for passage to the Citadel for Finn and Jake like they wanted. Shelby then immediately gets a call from his girlfriend on his cell phone saying she got the pony and named it "Speedboat." He then goes into Jake's ear to talk to her, though he appears to have some awareness of Finn and Jake's subsequent adventures in "Escape From the Citadel."
