Cookie Monster

Cookie Monsteris a Halloween costume for Cloud Cookie featured in Halloween Party events. It was first usable during Halloween Party 2014 and returned in Halloween Party 2015 and Halloween Party 2016. However, after the event period, the costume would no longer be accessible.

Being based loosely on a monster, this costume puts Cloud Cookie in a much fluffier attire akin to her hair alongside two "eyeballs" on the top of her head.

Her cane remains entirely unchanged from its standard appearance. Her shadow also remains unchanged, which can be noted by the lack of fluff in the shadow.

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, as Cloud Cookie has yet to make any new appearances in a Cookie Run game that would use this costume.
