Ruby Slippers

In MYTH
The Ruby Slippers, or Ruby Shoes, were discovered by Tabris at the Glowy Clearing in Episode 1 named The Red Slippers. While it is not clear what their purpose is, they fit Ozma perfectly. They are incapable of getting dirty, which Ozma claims is because of "science reasons."

In Oz
In the original Wizard of Oz, Dorothy Gale acquires a pair of silver shoes (ruby slippers in the movie) from the Wicked Witch of the West when her house falls on and kills her. These shoes give Dorothy the ability to travel anywhere in three heel clicks.

Notable

 * After Ozma receives the shoes, she uses one of her 'redstone contraptions' (a command block created by Casey for ease of travel in emergencies) to teleport everyone to the Goodwitch Home.
 * The skin itself was manually colour shifted by Casey in GIMP.
 * There are four total versions of the skin, but only this one was used in-game.
