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.
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.
