Xylophone Creeper

Xylophone Creepers are a strangely musical, passive, yellowish gold mob that posses the ability to create its own music. This trait is not shared by any other mob in the game. For idle sounds, a xylophone is played with two low keys. When hurt, they make higher notes.

Behavior
Xylophone Creepers are very rare and hard to find, but once found they are worth the search. They will follow players that are holding Rotton Gunpowder (an item retrieved by a Zombie Creeper) like passive animals following wheat. They will not despawn and continuously play xylophone keys that can be heard up to a kilometer away.

Habitat
Xylophone Creepers only inhabit Volcano Biomes, and because of their widely-heard xylophone keys they are easier to spot even from a far distance. Their golden hue makes it easier to spot in the dark areas.
