This quest is pretty much identical to The Elmon Crown. Only instead of taking place in the Ice Canyon it takes place in the The Great Ancient Ruins. Much like the Elmons the Trookies will steal items and accessories from you. You can get your items back by battling the Trooky Queen. You can find her in Lunar Palace as you are walking to the bottom floor. She'll be in one of the side rooms at the bottom of the north east corner and is easy to miss so keep a look out.
