What Should Chica Do For Her Trunk-or-Treat Party?

I'm so excited to be a part of The Reserve's Fall Festival on October 29th. It will be a night where you don't have to worry about your kids running out in front of a car trying to get a piece of candy. The Cajun Cuisine food truck will be there, a bounce house for the kids, food, treats, and most importantly the folks who are creative will show off their imagination with their Trunks.

It's a Trunk-or-Treat party, basically, every parents dream right? You drive up somewhere and don't have to walk block after block to keep yelling "Trick or treat!". Instead, several savvy adults decorate the trunks of their cars and wait for trick-or-treaters.

I have never been invited to be a part of a Trunk-or-Treat type of party so I am at a total loss here. I am creative in other ways, this whole being artsy thing has thrown me for a loop. What do I do? What is a cheap way to be a must-stop among all of the other cars? Yes, I want to incorporate my dog Olive somehow. I have no idea how to make my SUV look like a cute Trunk-or-Treat stop.
