Dr. Jekyll & Mr. Hyde

Dr. Jekyll & Mr. Hyde is a Halloween costume for Werewolf 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 character Dr. Henry Jekyll from the Gothic novella Strange Case of Dr Jekyll and Mr Hyde, this costume puts Werewolf Cookie in an outfit akin to the Dr. Henry Jekyll character. In werewolf form, he is in an outfit akin to the Edward Hyde character.

He now sports a black and white candy cane and a very dapper top 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.
