Have the Best Halloween Ever Thing!

Due to a bad childhood experience, Principal Hader cancels the Halloween carnival. CJ, Fenwick, and Crispo make it their thing to figure out why Principal Hader hates Halloween and fix it. Meanwhile, Crispo is made fun of for wearing what others perceive as a costume for little children. He then changes to a more dark costume to be cool, but later realizes that he should not change simply because somebody doesn't like a particular feature about him.
