Music Hole is a sentient hole in the ground that extends to an unknown depth. It has appendages that are retractable, and when extended cover its entrance in a woven manner. It first appears in the episode "The Music Hole," where it interacts with Finn, explaining how he is fortunate to be able to be seen by others. It appears again at the end of "Come Along With Me ," where it sings the eponymous song to sum up 'complicated emotions;" Jake is shown to be able to hear and interact with it as well.
Music Hole is binocular, with both eyes being blue and dark blue pigments that have the ability to form sillhouetes and images. Its tentacle-like appendages weave themselves over the "mouth," and appear to be innocuous.
- It is unknown how it knows characters such as Tree Trunks, Ice King, and BMO, if it is immobile.
- The Music Hole is voiced by Ashley Eriksson, who performs the end-credits "Island Song."
