Catch-all 'wastebasket' tag for ear accessories that don't currently fit under the other
ear_* tags. Usually this is an adapted (i.e. smaller) form of a hair, neck or arm accessory that is worn around the ear instead of their usual places.
Umamusume characters often feature these accessories as their "eardecs" feature prominently as part of their character designs (and to provide allusions to their real-world counterparts).
Note: Examples under this tag should probably be moved out into their own specific tags (using terminology similar to their hair/neck/arm counterparts) in the future once they acquire enough examples to qualify for their own tag. It may perhaps be a good idea to discuss such tag proposals in the forums first.
