Wicked Witch of the West

Wicked Witch of the West is a Halloween costume for Alchemist Cookie featured in Halloween Party events. It was first usable during Halloween Party 2015 and returned in Halloween Party 2016. However, after the event period, the costume would no longer be accessible.

Being based on The Wicked Witch of the West, specifically the iteration of The Wicked Witch of the West from Wicked the Musical, Elphaba Thropp, this costume puts Alchemist Cookie in a black witch's hat and robe alongside green cheeks akin to how Elphaba Thropp appears within the musical.

Her vial and book remain entirely unchanged from its standard appearance. The shadow was changed, though, as apparent from the visible hat.

Unfortunately, like many other Halloween Party costumes, this costume is completely inaccessible in any other Cookie Run game and it is currently not known if it will ever make an appearance again. However, this outfit appeared in recent official artwork found on social media.

Trivia

 * Both Cheesecake Cookie and Alchemist Cookie share matching costumes. However, unlike the rest of the The Wonderful Wizard of Oz costumes, these two are based off of the Wicked musical in particular.
