"ToyPicker" is a World of Warcraft addon that creates a button for randomly using a disguise toy. In Season of Discovery, these toys can be purchased from the Bubbles NPC in Booty Bay. In both Mists of Pandaria Classic and Retail, utilized toys can be found in the Toy Box page of the player Collections interface.
