It's Nightmare Night and Spike has no costume to wear. Luckily, Rainbow Dash might just be able to help him out. As the two hang out, they see a mutual benefit for pranking; Rainbow Dash can try to outprank Pinkie this year, and Spike can avoid spending two-and-a-half hours stuck at the pre-announcement party with Twilight.After all, it is the best night of the year for pranking.
Just a silly Slice of Life fic and winning entry in the SpikeDash competition hosted by the ever-vigilant YourNeighborhoodAlicorn. Because friendshipping is the best kind of shipping.
Special thanks to Mr101 for giving me the idea, and to Draconian Soul for prereading.
