Twisted horns were a very rare reward from the Squeal of Fortune. They have no bonuses when worn and are purely for decoration. When a male player equips Twisted Horns, his hair style is set to a ponytail, regardless of hairstyle when no head object is equipped, but is changed back after un-equipping it. Similarly, they change female players' hair to appear windswept.
They were again made obtainable during the Blast from the Past II Treasure Hunter promotion on 17 July through 22 July 2014, and once again through the Smashing Relics promotion from 19 to 23 July 2018 and from 16 to 20 July 2020.
