Harmonelid
From Tardis Wiki, the free Doctor Who reference
A Harmonelid originates from the Xoga system and is a creature that loves to share music. When necessary it can rapidly accelerate its growth and grow legs in order to help facilitate its escape. They are known to home in and settle inside peoples ears and while they don’t damage ears as such they do pose a risk to young developing ears which may be harmed by the presence of the worm in the ear. (DWAM: Earworm)
