The following are some item ID's that I basically just typed up at random to see what they would display. I'm not sure if there is a way to find a specific item ID that corresponds to WoW Plus' input, nonetheless here are some cool ones to use. Enjoy =)
P.S. these are used by going into the Misc tab, and typing in the <id/scale>, then selecting either unit, or mount and voila.
