Langwidere wants Glinda's Pearl of Pingaree, but there are other powerful pearls in the history of Oz famous for their magical powers such as strength, protection, and speech.
When West is telling lies to find Glinda's pearl, she says she enjoys "Gillikin Folk Music." Gillikin Country is the northern region of Oz, known for their dark, mysterious forests, dragons, and balloon people. Gillian Folk Music is known all across Oz for its use of magical woodwind instruments.
