Another year has passed, and Halloween has rolled around once more. Last year I took ponies to a trunk-or-treat. This year I'm hosting a costume contest.

While this is a sequel to Car Wash and its existing sequels, there's no need to read any of the other stories first.

The crossover event half a dozen people have been waiting for… A blockbuster fanfic three years in the making (or possibly cobbled together last night in a rush to get it posted in time for Halloween/Nightmare Night).

The Business Trip series crosses over with the Car Wash series.

All the ponies you love have come together under one roof for a costume party. My roof. I really hope my insurance policy is up to date.

I apologize for the cover art. This may be one of those times when not having any art at all might be an improvement...
