When Larry hears the story of Chanukah, he becomes instantly enamored with the holiday and announces that he wants to combine his two favorite holidays - Halloween and Chanukah - to create "Challoweenukah." When no one shows up for the first seven nights of the new holiday, Larry decides to publicize it by giving out candy to kids at the local playground, getting him in trouble with the police. Meanwhile, Marty and Debbie's arch-nemesis couple challenges them to a family Halloween costume contest.

Debbie creates and designs a unique purse and Jackie gets them booked onto "Shark Tank" to find an investor. When Larry joins them on the show, the outcome from their presentation is not what anyone of them - including the Sharks - expected. Meanwhile, Amber steps up to be Abby's choreographer for her big dance recital.
