Inspired by P.U.E.W.C. in this year's Chewbaccus Mardi Gras Parade, here's an idea I'd love to see made. Considering there's a million Rhino helms, and a Moose Hoody, why not add a Unicorn Helm? Ideally equipping this armor would give you both a Sparkling Horn and a Rainbow Mohawk.
It could also be a sparkling Miss Universe Tiara with Horn as seen on the PUEWC Master Midori, pulling Horny the trike float above. (thanks EnigmaArts.com for taking such amazing parade photos)
Doesn't have to be just a helm, could be a full Rainbow Unicorn armor set, with these fuzzy rainbow boots. (wizard not included)
Or a seahorse unicorn
Or just a single beautiful horn in the center of the forehead.
Whatever shape you made decide, Blizzard please make a Unicorn Helm for all the sparkling Unicorn enthusiasts that may play your game.
