We let our kids wear their costumes for play the rest of the year. They get worn more in a few play sessions than on Halloween.

Also, roasted pumpkin seeds are easy, healthy, and delicious.

I wonder if after growing, harvesting, shipping, etc. a Halloween pumpkin is carbon negative.

If I had to guess, probably 80% of the stuff I've received over the years as Christmas gifts ends up getting used very little and then unceremoniously put on a shelf or in the trash. And that may be a generous estimate.
