Shelby is now under a Halloween curse. Every year on October, he transforms into a more evil & crazy version of himself until the month is over. He won't remember a thing of his actions. He likes to get big & destroy as much as possible. He ditches the googles because he thinks it ruins his looks of being a destroyer.
Just a heads up. If he's hungry, run or you'll won't be seen until October ends. He can be negotiated if you have enough food to substitute.
