Trunk or Treat - Need Some Help - Prize to be Awarded

Last year our ward had a trunk or treat. We were able to take Jimito (our new name for Little Jimmy) with us and he was a hit. I hope we can take him again this year. Last year he was a gorilla. He couldn't say hi ll's that well so it was a crack up to hear him tell what people he was. This year he is going to be Captain Hook and Katie is going to be Tinker Bell.
As part of this Rick and I dress up and need to dress up our car as well. (I was going to post photos of our car but I have no idea where they are.) We were Jeff Gordon's pit crew. My mom had some awesome magnets made for the car... we have a Dupont Sticker, a 24 and Jeff Gordon's autograph. (They now reside on our fridge and washing machine.)
I need some help coming up with what to do this year. The thoughts we have had so far are:
The Mariner's Dugout (We have sweat shirts from the Mariner's game we went to)
Something related to the Bee's/Stingers whatever the heck they are now because I have a Bee's Jersey
Something related to Hockey because we have some hockey jerseys
An Ambulance - We have scrubs since Rick was in nursing, including some great NASCAR scrubs I personally like to wear.

My mom works for a sign company and is able to make magnets for our car and other things like that but I need to have enough time to get them made. Maybe we could continue the Peter Pan theme as Jimito was telling us who we were people in Peter Pan....I could be a mermaid and Rick could be Smythe hhhmmm I am going to have to think about this.

My request of you is to give me some ideas. I am open to anything! The person who comes up with the best idea and if you even help us figure out how to do it, well you will get a prize. Not sure what the prize will be yet but I will come up with something.
