I was a bit late, but assuming you ignore my unintentional hiatus, these are right on time ;)
here is a link back to the challenge.
Without further adieu, the results!

First:

For first place, we have the Very Scary Ghost made by KSB24

I love blowing this up, and the AI is awesome. (Make sure to try it at night!)

Second:

For second place, we have the Fighter - Spookycat-14 made by SimplePotato.

This is not only a good halloween build, it is a great jet as well!

Third

And for third place, we have the TheMouse As A Moth made by my friend Karroc9522

I did not expect myself to be part of this challenge! lol
