Ghostbuster

Ghostbuster is a Halloween costume for Banana 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 on the Ghostbusters film, this costume puts Banana Cookie in a the attire of one of the Ghostbusters. Her Choco Monkey is a ghost.

Her hula hoop is now a red laser beam based off of the laser beams shot out by the Proton Pack.

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, likely due to copyright reasons.
